Aim bullets

Been using 124 gr over 8.2 gr Vv N350 for 38 Super. No issues whatever. I like em.

They should still be fine at that velocity. Out of curiosity, what's your cylinder gap? Using minimum taper crimp?

9mm Para/Luger should only use taper crimp, ever, any kind of bullet, very moderate too. Just remove the belling and on ready round, measure mouth with calipers!!! And run your thumb against the bullet-case mouth up and down to feel if there is excessive belling left.

I use the 124 's in my 9mm Beretta and 165's in my 40 cal CZ 75. Zero problems and good accuracy.

Yes, but he stated that he was using a 158 grain bullet in a revolver. Typically, revolver guys roll crimp so I was just making sure that wasn't the case.

In fact, all you need is to straighten the case back out to remove the bell. No real need to crimp at all, as case tension will do what you need it to do. You can check if it's right by pulling incremental test rounds until you get to that sweet spot where it's not not quite indenting the the bullet, and that's where you set it. Our .38 Super (major) loads are roughly the same ballistic profile as what you're shooting, and I've never once had set back or c=forward creep in recoil.

Good luck
