Dude, every time I see you do that with your cigar I feel like I can smell burning hair! Yes, counterbores were an acceptable fix for muzzle damage, OUTSTANDING!
Another save. Outstanding work. Counterboring does not destroy accuracy. 9 Hole Reviews released a video today of a 91/30 Moisin shot to 500 yards with only 1 miss, and the bore was counterbored. Outstanding explanation Sir.
Both of my M-44's have counter-bored muzzles which were done during arsenal refinishing in Russia....and both shoot great. I don't think the one rifle was ever issued as it's pristine and likely didn't need the muzzle counter-bore...but I think they just did them all as it does no harm and is only a positive thing. Maybe for 'collectible' rifles a counter-bore is not desirable but functionally it's a great thing to have.
You gave this rifle a new start, what you did for this 100 some year old beautiful rifle was a blessing. Because of your hard work, this rifle will last another hundred years hopefully
The people complaining about "ruining" a historic piece are usually the ones responsible for it to be in such a bad condition in the first place. Having no idea how to do the proper maintenance and somehow believing that the accumulated gunk on it has historical value...I've seen so many guns which look nice on the outside but are rusted messes under the wood, it's a shame.
I always love when people go:"Oh there is this guy who has been doing this for 40+ years, but I have done it once in a shed, so I clearly know better!"
People are so damn sensitive. Nothing about that job "ruined" that barrel. That job kept that rifle in the gene pool for the next 100 years. Well done gents!
I don't understand the hate towards counterboring the barrel. That is a legitimate arsenal repair made by all the arsenals of Europe and beyond during the time period this rifle was made. The muzzles wore out from being cleaned by steel rods and got counterbored. Not a big deal. Were it my rifle I might have recrowned it too but that's captain's choice on a job like this.
Mark, you are a friggin WIZARD! I've learned a lot from watching you, but in no way could I ever master the art of smithing like you have. You clearly are the "Master of 5 Magic's" God Bless.
I think a lot of people having negative views of your work are probably just used to seeing the kind of idiots who don't know what they're doing destroy things based on the idea that everything old should be " improved " by bringing it to their perception of factory new condition. I hate when people do that to everything from a hammer or axe to a knife or a firearm. People need to learn the different between a rehabilitation and a restoration, and they need to understand that something is only new once.
I love watching your videos on these old war rifles and sporting arms of the past! The way you take the time to dial in a 0.0001" to counter bore this beauty and restore the barrel to shooting condition is a work of art! I have seen a few rifles having this done, and you could tell it wasn't recent, and it has been fired quite a few times since, shows the process works!
What surprised me about this wasn't the fact that the barrel got counter bored. It was that, apparently, there are people who consider that "ruining" a gun. Years ago I was looking at Mosin Nagant rifles. Virtually every example that's not a Finnish rebuild and dates to before the 1930 redesign has a counter-bored barrel. Any country that needed servicable rifles, but couldn't afford to replace their entire inventory, did that.
I did the same on a 1903 Springfield from 1933 where I assume soldiers in the past had worn out the front rifling completely away with poor cleaning routine. After counter boring and machining a new crown on it she shoots 100%.
Hey man machinist here. I don’t wanna be “that guy” because i know you know what you’re doing. But be super careful running any helical flute endmill in a morse taper drill chuck. They have a tendency to catch the material and pull the taper out of your tailstock and break your endmill. I wont say i haven’t done it in a pinch, but a micro boring bar is a lot safer.
The counter bore turns this "Hey, wanna see my Mauser?" into "Hey, wanna shoot my Mauser?" I imagine that there are a lot of machinists out there that would have run an indicator on the outside of the barrel at the muzzle, and called that good.
A lot of people forget that these are functional tools first and foremost, and are only worth scrap if they arent functioning properly. Those are the types of people who'll cringe at any maintenance and repair that isnt WD-40 and a barrel swab
Hey Mark, great content. I'm not particularly into guns, since I have no need for them, and by the end of the day they're just tools. but I do like old crap, history and mechanic ingenuity, and you deliver on all fronts.
People got mad over a counterbore? That's how a rifle like this would have been repaired by the German army to begin with. Some people are impossible to please. Gotta say, that's a beautiful piece, and the light pitting in the steel is very attactive. I kind of wish guns came out of the factory like that.
Ah parce qu'il y en a qui sont capable de critiquer ce travail !!!! Moi je ne me le permettrait pas. Mark est l un des meilleurs. Beau travail comme toujours
A counterbore is literally just shortening the barrel without it being visibly shorter from the outside. That's all. As long as it's done correctly the only effect it will have is the same effect that would occur if you shorten the barrel by the same amount.
I agree with keeping an old gun usable but i dont agree with sporterizing. If you want a modern gun get a new gun dont dress up a 90 year old rifle into a ruger american lookalike.
@@craigthemonke794Old mauser actions on bad barrels seem to be salvageable, ask Larry whatshis face. So I partially agree, Don't sporterise a good gun, but do cannibalise wrecked guns.
Arsenals counter bore frequently. The condition of the throat and muzzle is critical. It’s harder to deal with throat erosion. But you can get a lot of life out of a barrel after a counter bore
Love watching and learning techniques of manual machining, i developed a great interest after going to work at a shop where i had to teach myself how to run a lathe with zero experience.
Nice work my friend. Most might have “thought” this was a SIMPLE fix but you did the best thing all around. Wonder how a mod 70 would stand up to that same setup? Hmmmm….
Didn't the Finns rebarrel a lot of their Mosins with higher-quality Sako barrels, or was that just the M39? I know the M39s had both the new Sako barrels and improved open sights.
Good work, I've had to do a job similar to this. In my case, a round was lodged 3 inches near the end of the muzzle of a colt lightning in 22 that was completely rusted all through the bore. Saved most of the bore except that last 3 inches that had been plugged with a round+water+dirt+rust (Horrible storage on client side), discussed it with client and agreed to have the 3'' chopped. After that, indicated and re-crowned on lathe. Went to a range and the group at 20 yds was horrible, restoration for shootability was fine, performance not so much. Good job on your side
Counterboring was reasonably common to save barrels on military rifles. When I imported a batch of Nagant rifles, there were more than a few with counter bores several inches deep as an example…
Thanks man! I learned something today. I never thought of using the steady rest in conjunction with the 4 jaw to zero the muzzle. I like the way you think.
Very informative. I have a no1mark4* barrel that will get the same treatment. Guns not worth much but the experience gained in doing the repair will be worth the effort.
The cigar behind the ear... I'm dead. 🤣 I do the same thing with my carpenter's pencils and Sharpies. I even walk around with them like that sometimes. Wish I could stick a lit cigar up there, would make my job easier some days, but I work at a VA hospital. ☹️
There is a lot of truth in that statement. While a 'new' barrel could be installed, it ruins the value more than counter boring the muzzle, and many old mil surp have been counter bored, so it doesn't affect anything on this old beauty!
Is what you did there essentially the same as chopping that much off the barrel and moving the front sight back? Basically gave it a new crown while preserving the overall appearance of the rifle?
Well, if the gun belonged to Kaiser Willhelm, then it you can argue altering it is destroying a historical artifact. But this wasn't that. They made something like 91-125 million of these rifles and this wasn't in showroom condition. It really wasn't anything much more than a wall-hanger, so counterboring wasn't destroying it. And yeah, it'll give somebody the ability to experience "the feel" of using one of these guns, which brings history alive.
@@jaiseman5919 Would it matter if it worked or not? You're not going to shoot a gun with that much value. I really don't know what you would do to preserve it though.
Thanks for a “plain English” explanation of the lathe setup. I understand a lot of the work you do, but lathes go into a version of heavy lifting in your art I have never been able to wrap my head around.
A lathe can be seen as a horizontal drill press. You can put a bar of steel in the jaws, and use a file or cutting tool to modify the outside surface of the stock. You can mount a drill bit, reamer, in the tail stock jaws, and drill or smooth holes in the inside of the stock. A lathe is a very versatile tool, and if you do metal work, you should invest in a small lathe!
Yes sir - it's just, frankly, fascinating (and a little overwhelming) to consider the precision. Functionally, I "know" a bit of what lathes can do, but the operation, set up, and results? Man, it's all black magic, lol. I always enjoy Mark Novak's videos due to the explanation and the time setting up shots and going a bit "deeper" into some of the nuance and rational. @@jeffreyyoung4104
I have a Turkish Mauser manufactured in 1940 that when I first saw the front muzzle I thought it was a 410 Shotgun, but found out that it had been counter bored at some point in its life.
Not just the Turks. A LOT of Lee Enfields ended up with the same affliction. Folklore had it that an oiled piece of cloth poked into the muzzle, was an ideal way to preserve a barrel. This was, apparently, common among target shooters.. I eventually found the direct evidence in a forgotten cupboard. The rag had dried out and become "crumbly". Very likely that the decomposition of the oil had also produced an acidic residue. This particular one was living in a reasonably "dry" part of the country. There are several better ways to look after barrels. Counterboring / "auxiliary" rifling The latter, first. VERY difficult, fiddly bit of "engineering"; unlikely to be worth the expense, even if you found a "matchingg" piece of the same type of barrel.. Straight counterboring? Not just the Turks got up to that caper. In the "good old days", I scored a genuine battlefield "pickup' Russian SKS that had "patina" but was all there and looked like it had "been places". That chrome-lined barrel had been counterbored back about 3/4 of an inch to leave a crisp "internal" crown. Why not just lop off the offending bit? The folding bayonet locks over that proper muzzle section. What sort of revolutionary type would forego the ability to use a byonet?
If a guy did NOT have access to a lathe, would it have been possible to get after that rusty area with a stainless bore brush sufficiently to remove enough of the rust to prevent an unsafe condition?
That's a question with a dozen lawyers attached to it, not to mention moral considerations. There's no safe level of barrel obstruction. Notice Mark didn't aim for getting 95% of the obstruction, he removed it entirely. Hopefully making it safe for years to come and a thousand plus rounds. Any gunsmith would have to physically inspect your gun to give you an opinion.
@@marknovak8255 no Mark you didn't. you said you had "about a .030 obstruction that no amount of filing etc. would make it right" or something to that effect. I am not in the habit of arguing with other folks content, and I love your content, however I feel like I have been kicked around a bit for my question, which I though was a legitimate one. My contention, which I did not explain (my fault there) is that the barrel did not "grow" additional base material. the obstruction is iron oxide rust, and once removed, there will be less base material, and therefor a larger bore than the rest of the barrel. And as a result, there will obviously be no bore obstruction because there is now less base material than there was originally and all of the bore obstructing iron oxide would be gone. I think this could in fact be accomplished by filing, glass bead blasting, or possibly by many hundreds of passes with a stainless bore brush. the last inch of rifling would be trash as would the crown, and accuracy would no doubt be hot garbage, but I would also argue that it would be "safe" to shoot. Sorry... just felt like I had to defend myself a bit..
True, most people would assume that the counter bore was an original feature. In a sense, in a military rifle, that would not be a bad idea. Troops are well known for doing less than nice things to their guns and more than one bore I have seen looks like the gun spent a few days with the muzzle stuck in the mud and then fired clear.
Considering the German Empire's solution to a bad barrel was often to replace the barrel entirely, I think it is fair to counter-bore instead of throwing away an otherwise historical barrel.
Mark or whomever more knowledgeable than me please correct me here, but by doing this, the actual portion of the rifling that finishes engaging with the bullet is now internal to firearm so the true crown is inside? or is it since you are only removing the metal rifling that protrudes from the barrel internally, that whatever potion of the bullet that normally would be in the grooves is still able to touch the counter bored area and the crown is still at the end of the barrel as normal? I am assuming the second? Thanks
The crown is now at where the rifling ends inside of the barrel, the bullet will not touch the inside of the counterbored section, just like how a bullet traveling through a suppressor doesn't touch the baffles, assuming proper concentricity. Hope this helps

Troops are well known for doing less than nice things to their guns and more than one bore I have seen looks like the gun spent a few days with the muzzle stuck in the mud and then fired clear.
It amazing watching a master at work great video
Might it be an idea to blue the counterbore? For looks and longevity?
I've heard the Arsenals counter bored a lot of rifles for muzzle damage anyway.
I guess it depends on whether you want a functional rifle or a museum piece
It's your gun Sir . Do whatever you please .
Great work
Relining the barrel and precision welding of both ends to conceal the liner has been done in the past with excellent results.
Who paid the bill for that? Just curious......
Sounds great but unless you are paying yourself$$$$$$$$$$$$$$$$$$$$'ddddddddduh.
Considering the German Empire's solution to a bad barrel was often to replace the barrel entirely, I think it is fair to counter-bore instead of throwing away an otherwise historical barrel.
Mark I have a barrel vice can replacing the barrel be an option?
Bought a auction rifle that had that done to it. It shoots great very accurate
Beautiful result.
My kingdom for a lathe!
Mark or whomever more knowledgeable than me please correct me here, but by doing this, the actual portion of the rifling that finishes engaging with the bullet is now internal to firearm so the true crown is inside? or is it since you are only removing the metal rifling that protrudes from the barrel internally, that whatever potion of the bullet that normally would be in the grooves is still able to touch the counter bored area and the crown is still at the end of the barrel as normal?
I am assuming the second?
Thanks
The crown is now recessed.
The crown is now at where the rifling ends inside of the barrel, the bullet will not touch the inside of the counterbored section, just like how a bullet traveling through a suppressor doesn't touch the baffles, assuming proper concentricity. Hope this helps
Smarter then me on this stuff , Thank Mark cool video.
MASTERS at work!
