    The Mauser 98 also has a cone, it's inside the receiver ring, and the barrel seats up against it. The Springfield simplified the receiver by coning the barrel breech instead. Thanks for the video, I really enjoy watching them!

      Hi Vincent - You're right - I checked some of my Mausers and the ramp is good and helps - although the bullet tip can hit the flat edge of the barrel - as you note - the Springfield does a better job and the pre-64 does the best job at feeding without obstacles for the bullet tip. Thanks for writing.

    Dear USOG. a few weeks back, you said "Barrel life = a few seconds" ....That statement tumbled in my mind like clothes in a clothes dryer. I have a steel rifle barrel, off a pattern 1914 that was a CENTURION .300 win mag re-chambering. This keepsake represents the best part of my life/hunting. The barrel is throat eroded, and accurate no longer. I put 2800 rds thru it over 25 years. average velocity, 3100 fps (180 gr) I am dyslexic, but i have some good days. I always thought of barrel life in round-count. After some serious sawdust smoke from my ears, I have determined my barrel life to be 2/3 of a second. This is based upon your premise that bullets pass through and fractions of a second. My estimation is 1/4000 th of a second through my 24 inch barrel. This is approximation on my part. Thank you for igniting my imagination. As I live vicariously through your thoughtful, insightful uploads.

    I must be getting old because for a field rifle I prefer an Mauser-esqu or model 70 classic or pre-64 style bolt rifle. It's what I prefer and I'm limited in choices being primarily a left hand user. The actual reason for this preference is mostly for the heavy duty extractor. I can't afford those euro straight pull rifles like that Blaser (highly overpriced), but do have lefty model 70 classic,

    I am a fan of Winchester model 70's made between 1980-1988. They are push feed. They are the smoothest, quietest bolt actions I have ever felt or heard. For instance, I just purchased a Sauer mod. 100. UA-camrs falsely claim it has a super smooth action . Nothing could be further from the truth. The bolt "hangs up" and "drags" compared to my super smooth Win mod. 70's.

    Hey it's me again Mike. Another fine educational and entertaining video. Aside from things just being worn out, I always thought that the biggest feeding problems were caused by not operating the bolt vigorously enough (which a gunsmith educated me about a long time ago) and the relative shape of the cartridge. 300 H&H being the best ever and any of the ones with very little taper combined with shoulder angles that were almost square the worst. Think WSM or WSSM. I suppose I should add rimmed cartridges not aligned properly in the magazine which would be operator error. I have a Siamese Mauser 45-70 that whoever built it originally just didn't do a very good job. It wouldn't feed worth a tinker's damn. All it took was getting it to a good old time gunsmith who knew his business and happily paying for his service. Works like a charm now. Happy hunting boys and girls.

    @chipsterb4946 Рік тому +1

    There are 2 distinct advantages to having a barrel extension that the bolt locks into, instead of the barrel screwing into the receiver and the bolt locking up in the receiver. First, the barrel manufacturer can ream the chamber and cut the locking surfaces in the barrel extension without worrying about the receiver dimensions at all. IOW getting headspace correct depends on the barrel/barrel extension assembly and the bolt. The receiver is no longer part of that equation. Second, the receiver isn’t part of the chamber anymore. This means that the receiver can be made out of aluminum like my lightweight ‘81 BLR lever action rifle.
    Frankly, I don’t understand why some manufacturer hasn’t taken this AR approach and applied it to a budget bolt action rifle. The Browning BLR is a wonderful, modern rifle that just happens to be actuated by a lever. A bolt action with the same lockup design would be far easier to make than the rack & pinion mechanism of the BLR. Heck - it could even be disassembled by the end user! (As far as I can tell, disassembling a BLR qualifies as a very BAD IDEA because of the lever action timing.)

    • @UnitedStatesOfGuns

      Thanks ChipsterB - Can be done and coming soon. Aluminum receiver; aluminum bolt body or polymer; steel bolt head - carbon barrel with steel locking lug recesses in a press fit barrel extension. Polymer stock. Maybe people would want such a thing.
      I agree on the BLR - I had some show up disassembled - getting the rack and pinion timed right again etc...is not a great idea.

      Hi RG - Thanks for verifying - maybe I was thinking of one of the pre-64 copies - which are the same as the pre-64 except for the coned breech. The Maple Grade is superb in looks and I'm glad they kept the feeding. The Remington is okay but I remember many times having to do the backup the bolt a bit and push again - with many bolt rifles - not only the Remington - if the bullet tip somehow hits a flat area at the back of the barrel.

    *Yes, that was interesting. I was not aware of multiple rifle makers using the coned breech. Due to limited exposure, I have only seen the 1903 or '03A3 and '03A4 Springfield using that coned breech. Your demonstration clearly showed the benefits of that feature. The new 'lugs in barrel' sort of system is also interesting.. I can easily see how that might gain some practical strength or more fully contain the cartridge. I will agree with you. If anything goes wrong or a cartridge gets stuck in that chamber of the R-8 or anything similar... getting a stuck cartridge out might be a minor challenge. Interesting stuff. Sometimes, it is amazing that people somehow got all of that to actually work.*

    The receiver ring in most bolt action rifles has a cone, but I have feed polished feed ramps on rifles that should not have not been , and I'm talking many different mauserdbimandbbotherbmikkitary boot actions.
    About half are preffesionaly done in when made or when being rearsenaled and some the armourer or even individual soldier / would do.
    The M91/30 wartime production rifles did not have feed ramps so many soldiers would 1. Bend the tip of the mag follower or put in a type of feedramp by kind of copying the older pre war rifles.
    Controlled feed is nice but In modern rifles I would not say it's a must unless your going big game hunting.
    Some other rifles would also use the shape the mag feeder to do this.
    I was in the UK army cadets (not that long ago) and before I finished and moved to the zuSbthey changed to a Civilian .22lr modern rifle.
    On our range we had 2 types of converted .22lr SMLE one was a single loader the other had a magazine but the rifle was actually more heavy than a standard SMLE as it had the same barrel profile and no idea if it was a .22lr perminant insert or a .22lr barrel, you realy had to open and close the boot smartly for it to feed an eject, a crazy heavy .22lr but it was very accurate and the one with the 5 round mag was fast to fire.
    The most popular .22lr rifles we had where when a cadet died from a falling wall and as he loved shooting they purchased 2 very nice parkernhail new production (I think it was the 60s) Martini action target rifle with free floated bull barrel and some of the best iron sightdbi had used with probably the best adjustable stock for the time, It was kind of sad to see the memorial engravings if a 17 year old.
    We had 2 straight pull SA80A2s that where never really used one had an open sight one had a susat.
    But it was for familiarisation then we had a rack of standard issuie SA80A2 with Susats.
    We had a few older L1A1 wood stocked FAL rifles
    2 "official conversion" 7.62x51 NATO SMLEs
    A few .303 SMLEs
    1 Marini Endfeild in .303 and since we where in Wales it was kind of a favorate (the movie Zulu)
    For weapons familiarisation we had a Canadian 20" A2 style of M16 with a flat top but did have a carry handle (we realy liked those)
    An AK 100 series full length in 5.56x45 NATO
    One no idea where it was mad but a possible war prophy 7.62x39 milled Chinese spiker AK
    (For weapons familiarisation)
    A few 5 shot olympic style target pistols in .22LR
    Some standard issuie browning High-powers
    1 Sterling SMG
    And one WW1 98 a few WW2 98ks, a 6.5 Caranco and a 6.5 Arisaka
    Then some obsolete caliber stuff like a martini Henry.
    We could shoot as much .22lr , 5.56 ,7.62 and 9mm NATO due to huge stockpiles and the fact it did not cost anything.
    We would sometimes get grates of surplus .303 some had hangfiresband where awfull some where OK. Would get a limited amount of 7.62x39 (I think it's why they got an AK in 5.56)
    If we wanted good .303, 7.62x39 or 8mm Mauser we had to all put some money in the pot to buy it usually Romanian steelcase or surpluss 8mm, Chinese steel case surplus 7.62x39 then new manufacture or newer surplus .303 that shit well but removing the corrosive salts was not fun.
    Ammo was allways a reasonable price since even if you have a firearms permit in the UK you can only have a certain amount of rounds (can have as much reloading components as you like) so no hearing or lack of ammo.
    But since it was the millitary they could buy tax free cheap in bulk.
    Even after moving to the US I have allways preferred Cock on close.
    But in the UK you could buy a decent Europian over and under that had nice wood with extractors and a single trigger with decent blueing bljustndosrse roll stamp (engraving)
    Many where sold with an oversized stock as you would get a gunsmith to fit the gun to you.
    A new good shotgun would be under 350usd
    If you got if from a dealer that could fit they would charge about 50 to fit, sand and engrave but if you wanted them to finish it it was another 30.
    I have never seen this service offered in the US but it does involve pointing a closed O/U at the gunsmith...
    In the US spark from the Turkish stuff they cost a fortune and so many shotguns still don't have ejectors, most still have 2 triggers and many still have hammers and that's new production.

      Hello TF - Many bolt rifles have ramps that try to direct the cartridge into the chamber - Mausers often have them - and they work most of the time. The true coned breech though - works all of the time - there is no surface for the bullet tip to get hung up on. The Springfield has a sort of cone as well - which might be the semi-coned design you mention. Thanks for the note.

    Amazing video! I checked with my two Mausers, and they behave a little differently. One is a 1923 Mauser 98 Waffenfabrik Oberndorf chambered in 6.5x55 Swedish. I can feed as slow as I like and the bullet goes straight to the hole in the barrel. The other one is the reworked Mauser 98 into the Kongsberg M67 target rifle chambered in 7.62x51 NATO, and this one is not perfectly going straight and the bullet touches the edge of the barrel and I can feel a little resistance there. Both actions are not particularly smooth compared to f.i the Tikkas. I can imagine three things here to explain this. One is the extractor is worn on the outside right on both my rifles so I guess that creates some resistance. The other thing is the thumb cut away where the Oberndorf bolt crashes a little but the Kongsberg don`t. Then the third thing is how loose the bolt is in the receiver maybe they had to make it like this to ensure function under all circumstances in the war trenches.
    Sidenote and a little off topic: The Kongsberg M67 target rifle was not preferred over the Kongsberg (and Steyr) Krag Jørgensen target rifle because of the krag had a very smooth bolt operation. But in the rain the Krag had a problem, it only had one locking lug in the front, and the wet cartridge would cause the cartridge to move slightly backwards causing a twist that sent the bullet up right or down, dont remember which it was. The Mauser did not have this problem and was therefore the preferred weapon in field outdoor shooting. So many shooters owned two rifles until the Sauer 200 STR came and replaced the two in 1990. Sorry this was so long post.

      @UnitedStatesOfGuns  Рік тому +1

      Hi Torbjorn, Thanks for the post - not too long at all : ) As you know I have a few Mausers and some feed well and some don't. Much seems to have to do with bullet shape of course - and how the ramp interacts with the shape of one or another bullet.
      I didn't know about the Krag in the rain. Quite interesting. Theoretically headspace should be the same; wet or dry - but who knows.
      The modern rifles are fantastically smooth - the Tikka etc... Those with polymer mags with polymer followers tend to feed less well as the plastic wears away - but a new magazine solves this. I still find the odd time that a particular bullet shape hits the back of the barrel - but not too often; I think it happens more than one knows as speed of operation makes the impact of bullet nose on barrel hard to notice. The deformed bullet tip would account for some of those mystery flyers we all experience from time to time.
      Thanks again and good shooting!

      @@UnitedStatesOfGuns About the Krag there's a good Wikipedia article in norwegian I here used google translate on the subject of oil or water on the cartridge. It's rather long:
      "Hit point change
      All the locking mechanisms in the sliding case of the Krag are located in the three to six o'clock position, and are thus arranged asymmetrically. This makes the locking mechanism somewhat weaker and more susceptible to impact point change. The dedicated locking lug is located at the front of the breech head, and in addition there is an additional locking lug running along the breech. With the breech in the locked position, the main locking lug will be positioned on the underside at six o'clock, and the additional locking lug on the right side at just above the three o'clock position. The angle between the two locking lugs is actually less than 90 ° . As on most other cylinder lock rifles, the lever arm functions as an extra safety, but this too is in line with the longitudinal locking tab.
      With the Krag, it was often observed that the impact point was moved to the left and up if you shot outside in rainy weather so that the rifle and ammunition got wet, or if there was oil in the chamber. According to experience, the problem was greatest with heavy (thick) barrels used for competitive shooting. The phenomenon is due to less friction between the fired cartridge and the chamber causing more of the force from the recoil to go towards the breech head, which then twists to the side. With a dry chamber and dry cartridge, there will be good friction against the chamber walls and the phenomenon is hardly noticeable. Point of impact change due to changed chamber friction can also be observed on rifles with symmetrical locking if the locking lugs do not grip equally, but is more evident on the Krag due to the asymmetrical locking without attachment point on the left side."

    The Krag is the smoothest bolt action I ever used. Likely due to the single locking stud? Thank you for sharing. Love learning new facts on rifles. I don’t know if that has anything to do with feeding or a separate issue.

    I bought a brand new USRAC Model 70 Short Action Featherweight (chambered in .308 Winchester) around about 1990 and it had a coned breech. I sold it because the first shot from a cold barrel would always land in the same spot BUT 5 shots prone @100m would be 2-1/2” to 3” i.e. just under to slightly over 2.5 m.o.a. AND a 10 shot group would be ridiculous. If I cannot practise via positional shooting competitions, a bush hunting rifle is no use to me. NB For the benefit of anyone who is arithmetically challenged, 1 m.o.a. @100m = 29.09 mm; 2.5 m.o.a. @100m = 72.725mm; 2.5” = 63.5mm and 3” = 76.2mm.
    Another guy in our club had a USRAC Model 70 in 7x57 that was much better behaved.

      Hi Michael - I know what you mean. I had this happen to me several times. I have no explanation. It isn't free floating, chamber problems, polishing the bore, or anything else. Some barrels...don't shoot. : ( But there are lots of barrels out there : )

      @@UnitedStatesOfGuns Early days with hammer-swaging (hammer forging being a marketing term) appear to have been a painful experience for every company going down that route. I understand that Winchester Featherweight ‘hammer forged’ barrels had improved significantly before FN moved barrel production to South Carolina.
      The big problem with producing such a slender smooth-finished barrel by that method, seems to have been the removal of the mechanically-formed hard skin by that process which, according to a deceased gunsmith friend of mine, allowed the barrel to expand radially as it heated up. Sturm Ruger, as I recall, bought their first machine for shotgun barrel production and later purchased a larger machine for rifled barrel production. They have also steered clear of the extreme external machining required for the Featherweight barrel.
      The L42 Sniper rifle barrels were ‘hammer forged’ but traces of the process were left on the outside of the barrels, which tells you something about the British experimental test results when developing those barrels.

    Great video sir!! I am a great fan/collector/shooter of single shoot rifles. I have a question, if you have time sir. I would like to add a martini rifle to my collection, with that being said. I'm considering one of the newly manufactured Damko Martini rifles in 30-40 krag caliber. My question , is the martini action strong enough for the 30-40 krag? I don't understand fully how the martini action locks up and the bearing surfaces with regard to the breech block pivot pin geometry, and loading on the tip of the action operating lever. Thanks again for the great work ! Best regards, W Paul Graves.

    • @UnitedStatesOfGuns
      @UnitedStatesOfGuns  Рік тому

      Hello Paul, Thanks for asking. The Martini is quite strong; in some ways similar to a Savage 99 in that the bolt is raised by the lever and wedged in place against a significant locking ledge. I've owned Martini's in many calibers, including 7x57 and one 7X66 Vom Hoffe SE. I don't own a Damko but have heard from viewers that they put out a superb, strong action. I'm hoping to have one soon. Good luck and good shooting.

    Does the bullet getting snagged affect accuracy? It seems like scoring the bullets would be bad, and some bullet types would be more prone to scoring than others.

    • @buckaroobonsi555
      @buckaroobonsi555 Рік тому +3

      It can affect accuracy. Soft lead point bullets where they have exposed lead for the tip of the bullet are most likely to be affected. Since most people hunt with rifles more than compete with them it is not an issue. Also the type of bullet you use for accuracy in competition are less prone to this form of damage. On a bolt gun the forces involved for most of the loading is not that great. On a semi-auto where you have fast, sharp, machine forces and a powerful spring doing the loading bullet damage is more likely. The Germans spent a small fortune to build a semi-auto 300 Win Mag sniper rifle that would not deform ammo. Like the Walther WA 2000. In the 1970's and 1980's they where $9000 to $12,500 rifles to do what a controlled round feed+coned breech face on a Pre-64 style Winchester Model 70 was doing at the time for under $400. You also have a higher chance of deforming the bullet when you feed from both sides rather than from a center feed single stack situation. Push feeds are more prone to damage the tip of a round as well.

    The slickest feeding rifle we have is a pre 64 M70 in 300 H&H. Those long tapered rounds feed so well it is difficult to feel them chamber. It will also feed empty cases just as
    well as live rounds. One more added feature of this combination is you can put 4 in the magazine. It is the only belted mag cartridge that because again of the taper of the
    case will allow you to get a total of 5 rounds in the magazine.
    The short fat cartridges are not good for feeding out of a bolt action, and the limit capacity. Also they are very hard on the throats of barrels, and unless chrome plated will not have a long life.
    To get the performance out of them, the pressures have been raised to over 60K psi. Many of our older designs if loaded that heavy would outperform the shorties as well.
    There were reasons our manufacturers did what they did back in the day. IMHO these rules have been disregarded to sell new cartridges and new rifles to unsuspecting new buyers.

    • @UnitedStatesOfGuns
      @UnitedStatesOfGuns  Рік тому +1

      Excellent comment. That is all correct. Most or all of the principles of cartridge design and pressures, feeding etc...were well known by 1910. Increasing or decreasing cartridge length, pressure, bullet weight, action length, barrel length and weight etc... these are mostly marketing exercises - which are valid as well but for money related reasons as opposed to science.
