Ultramax 44 Mag SWC Leading?

[NewWorldBlues]

Will the Ultramax 44 Mag 240 gr swc traveling at 1360 fps lead the barrel of my 4" 629?

I would avoid Ultramax ammo. At least one person on this board had a ka-boom with Ultramax ammo.

flop-shank,

I already have 10 boxes so I'm going to have to take my chances this time.

I sent an email to Ultramax and they got back to me and said I'd probably have a little leading but it shouldn't be too bad. They said no gas check, and the lead is 5% antimony. I'm not sure where that fits into a soft to hard lead rating.

The guys in the reloading forum could tell you.

I'll post it over there. Thanks flop-shank.

You're welcome! I'll go over and have a look, since I'm curious myself.

BTW, that's a great signature line.
