anyone ever seen a carbine re chambered for a 357magnum

This comes up every now and again. To me its a very expensive solution to a non existent problem. .30 Carbine and .357 Magnum are pretty much ballistic equivalents when fired from a rifle. The only possible reason I can fathom would be the heavier bullets available in .357 Magnum.

Heavier 357 mag bullets might be too long to fit the magazine. Expect a reduced capacity when using 357 mag in a carbine magazine (five to seven rounds at best)after it has been reworked (magazine lips) to work plus the opened-up bolt face provides little support if any to the cartridge. Semi auto pistols that use the 357 mag cartridge have special magazines designed for the 357 mag.

Bolt action and break open rifles are more adaptable to cartridge changes, especially break opens. Semi-auto military rifles were designed around a specific cartridge, evaluated, tested, refined and tested again, before ordnance would open the purse strings to produce the weapon. Generally speaking, the Garand will work best in 30.06, almost as good in 7.62x51, and pretty well in .35 Whelen, in part because the case body is very similar to 30.06. The carbine was designed for the cartridge, or vice versa, but they were designed to work together for maximum effectiveness. The mags, the mag well, ramp, gas system, slide weight, spring, etc. were all tuned for that cartridge. If you want more bang than that, you might want to buy a commercial rifle.

I have seen carbines modified for 44 Automag? and 357 automag! Also I saw them because both were damaged during fring because of the bolt face modification-- The bolt face was opened up and the extractor had been thinned out extensively-- The extractors broke on both of these regualarily!! The guy that had these was a gunsmith in the Chciagoland area and he had a bunch of odd ball rebuilt rifles etc!! He also had a 6.5 type 99 ?? Jap Rifle that some moron reamed the chamber out to 30-06 spec's!! He thought it was a 7.7 ! Actually he fired the rifle one time and the rifle did not explode because they were using a lead bullet reload in it!! If I remember correctly the case head still melted but the rifle looked undamaged ! So who knows?? That rifle may be floating out and around somewhere right now!!

Be glad you can't find a bolt for the .45 Winchester Magnum. The mans name I think was La Flame or something like that who made conversions of M1 carbines into .45 Winchester magnums. As I said before he was only in business a short time before he disappeared with some unhappy customers looking for him. His conversions were not a success.
