I've been loading 45acp pretty successfully for a few months now. I finally got some 9mm cast bullets and after trying some loads out, I am finding I have bullet tumble out of both my m&p's(full size and compact).
I'm shooting 125g RN cast bullet(.356), 3.0-3.3 g Clays powder and S&B primer.
I get significant leading and wild inaccuracies. Factory ammo shoots fine in both guns.
I slugged both barrels today. The full size I get .358, compact 3.56. I've tried loading with no crimp at all but that doesn't help. I finally pulled a bullet that I had loaded and the bullets measured .353-354. Id say I found my problem, I just don't know how to correct it. How do I keep the bullet from being "resized" when I seat it?
thanks
