Very well illustrated and presented. Only nit pick, and a small one, is the ogive is really the entire portion from tip to bearing surface contact. So, one is really seating bullets focusing on that point.
very good explantation. Thx. Question: if the barrel freebore prepared to 308 Berger 200.20X, how possible reload with Berger 230 gr Hybrid OTM tactical (30112) without reaming?
So I have a 7mm rem mag I got from a friend. It’s an interarms mark x (Mauser action). I can literally seat bullets out as far as possible and still not hit jam point. I’m confused as hell. I just started reloading this year. I can seat to 3.390 and still fit in the mag. I’ve seated a bullet just a few thousandths into the case and it still doesn’t jam. Now my ruger .270 jams real soon I can only seat my bullets out to 3.229 which is about 30 thou off jam point.
That is interesting. The 7 rem doesn’t have much of a throat so it should be hitting sooner. Is it possible they had a custom throat cut longer than the standard? Some people did do that so they could use longer bullets.
@@longrangescience according to my friend it is all original and he’s only shot 500 rounds thru it. I can’t get it to group consistently at 100 and I know it’s not me or my ammo cus my .270 is under an moa. I’m now going to try a different bullet and after that I will switch scopes and test that. I may be getting a new barrel tho 😂. Thank you for the response
If you were to rebarrel the .243 can it and other traditional chamberings be made with some freebore to accomodate longer bullets? Thanks for the video.
Absolutely. There are throating reamers that can cut the throat longer for any caliber. If you’re going the custom route then you can get faster twist rates as well. Any decent gunsmith should be able to do that no problem.
Very good video :) although I have a question. So I’m looking to make a barrel chambered in 22 hornet. I’m new to gun smithing but I do know how to rifle the barrel and a few other things. What I am kinda struggling with is how to chamber the 22 hornet. Since it’s a weird shape and only slightly tapers I’m wondering if the chamber has to be exact or if it can be a bit wider or maybe even just straight, the reason for this is cause chamber reamers for the 22 hornet where I live are very expensive and rare so I’m thinking about trying to chamber without one. I know if it’s wider the case will expand so can this be reversed by reshaping and trimming the case? I’m looking to reload the spent brass. Thank you :)
Thanks! But I would recommend against cutting a chamber without the right reamer. Just because all the dimensions, angles, and transitions are so critical. If it’s oversized, the brass can over expand and rupture. If it doesn’t rupture, it will be oversized and significantly stressed during resizing, leading to cracking, case head separation, or a few other things. Also, straight usually doesn’t work because the case fills to expand the chamber and a taper helps with extracting the case. If it’s truly straight, the case is likely to get stuck. I know it sucks, but you should be able to rent one a lot cheaper than buying one
how hard does the bullet hit the lands? Example, what if you had a 9mm bullet at .355 inches, what would the land diameter be? Smaller .354 or bigger .356? And how about the bore? Must be a decent size bigger? What if the 9mm wasn't rifled, what would the bore be then, .356? Sorry, just started learning. I been searching for these specific answers but can't seem to find them.
7 thou per 100 rounds??? Wow!!! Do you find that to be fairly common across many cartridge/calibers, or just the 6 CM??? Everyone has heard the stories about how the 6 CM has a short barrel life and eats up barrels compared to other cartridge combos.
I know! It’s more than I thought it would be and defeats the whole purpose of loading to the lands. Ive heard similar erosion for other 6 mm and 6.5 calibers people have used in competitions but this is really the only one I’ve measured. I’m sure some are better and some are worse, but it would be interesting to get measurements on a large variety of calibers
Didnt you see that real gu smith chanel, the host, (i forgot hos name) daid that 6.5 creedmore had all types of factory ammo problems, at a time when everyone wanted one cause of the Bradley Cooper movie...
His name is Randy Selby and I've enjoyed many of his videos. He also said contrary to popular belief the 6.5 Creedmoor even on a bad day won't cure cancer. Well we all know that and I have nothing but respect for Mr Selby but I've noticed he doesn't seem to talk well about anything Hornady produces. I'm not saying he's incorrect, I really don't know and I've got 2 rifles both chambered in 6.5 Creed. They both shoot like lasers one is a factory brand the other a custom build. I know this is a love / hate round .all the smack talk about it made it that way. These being the only center fire rifles I've owned I cannot compare with others but hunters with typical deer calibers don't believe I hit golf balls out to 300. Never tried further because that's as far as I have. I haven't shot in much wind either so... It has been a great cartridge for me. Again no disrespect to Randy. I'm sure he has a point.
@@Lexidezi225 I don't doubt that. I got my first center fire rifle at 59. I'd shot some high powered rifles in my teens mostly 30 06 s that my friends hunted with. I asked permission to get a deer rifle but was told, No! They are too dangerous, here use this 12 ga. I still think that's a little funny. I bought a RPR in 6.5 Creed then a custom rifle from GAP also in 6.5 Creed. It's all I've shot to amount to anything. Never thought it was a magical round although I saw where someone said even on a bad day the Creedmoor can cure cancer. Well that's not true. It is a magical round for me. I've recently gotten 22lr and aspirin tablets at 50 , pennies and thumb tacks all have been had.
@@Lexidezi225 Just outa curiosity have you ever shot golf balls at 300 yds with no back to show where and how much your off if ya miss. Try it and let me know. I shot the first with RPR missed 1st and hit second. i tried again with GAP rifle and hit two in two shots. A golf ball is app 1.5 inches in diameter. That's half moa at 300. I'm not bragging nor am I trying to say I'm a natural born shooter. I'm 65 started 6 years ago shooting. I've since downgraded to 22 lr because ammo cost and availability but mostly I didn't have anywhere over 400 yds to shoot. I've got 200 out back. Try a penny at 100 , golf ball at 150 and aspirin tablets at 50 then thru the hole in a half inch nut. < lucky shot. Lol. With 22 lr. I quit hunting years ago but shoot some every day possible. Good luck.
If your barrel is eroding, and you have plenty of barrel to work with, why don't you cut the chamber deeper and cut the shoulder of the shank deeper as well to, in effect, have a new barrel? Especially if your barrel has no timing needs, you could cut a bull barrel a couple of times and save the cost of a barrel at least once, if not twice, in the life of the rifle! I have a rifle that would need an entire new barrel due to headspace if I did not cut the shoulder and chamber again, which would make the project too expensive due to the amount of work, if I had to add the cost of the barrel to the job. In my case, by removing the old barrel, cutting the shoulder back by one thread depth, and reaming the chamber, I will have solved a headspace problem, and the only cost is the labor of the machine work. And the rifle will have another 50 years of life in the family, plus, the barrel will remain original! But in your case, by cutting the shoulder and chamber, you get a fresh barrel, without the cost of the barrel, unless you have spare barrels laying around?
That is actually an option people use. If you have the resources it makes sense sometimes but for some its easier to just get a new barrel. The other issue is fire cracking. I’ve seen cracking from the heat and pressure extend halfway up the barrel in some cases. And that wouldn’t clean us as easily
Best video so far on the Tube. Thank you for taking the time to inform us.
Thank you! I’m glad you like it

hi mate . 40 mm for lathes spindle bore its good for barrel work or need 50 mm.
