I was wondering if anyone has built a semi big bore, 450 marlin, 50 AE or things close. I was thinking that it may be possible to build one on a BAR short action carbine, I would like something with more punch than my deerfield in 44 mag.
Any ideas would be great.
tks, Bruce
 
The BAR would work. I have seen mention of a very time consuming and expensive BAR in 458Lott. That would be fun. 458Win mag would be easier though. Trying to find a smith who is willing to try it would be a chore. Good luck
 
I've throught for years that the BAR should be made in .450 Marlin. THey already make it with a magnum bolt face and they already make .458 barrel for the BLR in 450 Marlin. I bet it would sell!
 
I saw some photos and an article in a French magazine about a .458 Win Mag Garand. From what I understand, rebarreling the BAR is not as simple a task as the same job on a bolt action rifle. Perhaps it is a better question for the gunsmithing area of the forum...
 
I think the barrel would be the expensive part.

They make BARs in .338 winmag, which is the same case as the .458, but with a smaller neck, so I'm thinking the mag and feeding system would need little or no work. BAR barrels are not as simple as barrels for savages/remington's however, and would cost more. A smith would also have to figure out how small a hole to make in the bbl to vent gas into the gas system, which could take some time to experiment with, and therefore some $$$.

I agree that this would definitely be a nice rifle however.
 
I always thought a semi-auto carbine chambered in 45-70 would be fun, use a reliable action, make it out of stainless and you'd have one heck of a tough animal stopper.

.458 Sa

About 10 years ago I had a .458 WM built on a BAR, it worked fine with pointed bullets not so good with round nose or flat nose bullets. It reduced mag. cap. to 2 rnds. It was so heavy that it should have had wheels on it. It was fun to shoot but not what I wanted in a semi.I sold it to a man in BC and as far as I know it is still sending big bullets down range very quickly.

Who did the work for you? How much did it cost?
 
Thanks, I do like the idea of the 358 but 450 would be best. Looking for bush thumper,,, 458 is too much. I wish the bushmaster was available to hunt with. I may be able to get Doug at epps to do me up a short trak magnum rebarelled to 450 or something like it.
I agree, someone should make it it a semi for us bush bear and deer hunters.
