Forgive me if this has been covered someplace (I could not for the life of me find anything regarding the following question), but I just picked-up a 629 PC V-Comp this morning.
Being this is my first .44 Magnum, and also any handgun with a compensator, I would like to know definitively if SJSP rounds are okay to shoot with the compensator on (e.g., won't shave the lead; or worse, blow up the comp)? I'm a little confused over which ammo should be used with which shroud. Any input is greatly appreciated.

Just no frangible ammunition

That's it? Good to know.
I picked up a box of 50 Magtech 240gr SJSP-Flat to try it out over the weekend. I plan on taking advantage of some hand-loads my brother-in-law makes up. He shoots .44 Magnum pretty regularly.
I know everyone knows what a 629 looks like, but here it is anyway:

Very nice revolver. Not to disparage your brother in law ,consider carefully using someone else's hand-loads. Personally I have a rule against it, But that's just me.

What the hell is that on the end of your barrel?

Completely understand your positioning. I shoot with him quite often, so I know his typical recipe; they're on the milder end. It also gives me a chance to learn a thing or two from him about loading one's own.

You mean the compensator shroud?
