Greetings all,
Earlier this year I found a couple of NOS 10 inch blue bull barrels, one in .32 H&R Mag and the other in .30 Carbine, and since I was messing around with single actions in both calibers I couldn't pass them up.
1) I recently read about the .32 mag barrels running .309 normally, and since I normally size all my .32 mag lead bullets at .314 I am a little worried about how they will perform. I had for no good reason assumed that this would be a 'normal' .32 barrel and I really liked the idea of being able to share ammo between a Contender and revolver pair. I have read some conflicting posts on the question if this .309 bore is an issue or not, and since the barrel is NOS I haven't rushed out to test it yet.
2) From a ballistics standpoint realistically will either one of them really dramatically outperform the other? I think that the .30 carb looks like it should run hotter and work better with heavy bullets, but is it a practical difference? All that I would do with either one is target shooting or varmints.
Any particular thoughts? Should I just use them both and not worry about it?
Thanks,
Danny
