You need to have it examined by a gunsmith
Do not attempt to fire until checked by a good gunsmith.
sure - clean it afterward
Absolutely not! 2 3/4" only!
You can shoot 45 Long Colt or .410 shot shells with this weapon. 45 ACP rounds will not work properly.
I have a Remington model 31 in 16ga and i shoot regular low brass shells in it and it does fine, it would depend on the type of game you are hunting. High brass shells are for more power and longer range.
Have it examined by a good gunsmith
It will shoot any type it is chambered for.
No. But there are revolvers made to shoot .410 shells that also fire .45 Colt cartridges,
if think when you put a 357 cartridge in your model 637 the tip of the 357 'might' stick out the end of the cylinder. that tells you NOT to shoot 357 cartridges in a 38 special..........
Yes I own one but you must turn the spring around.
If it's a 16 gauge shotgun, the shell length is 2 3/4 inches.
Yes, I don't think you should have a problem, but your pattern may not be consistent.
