No issues since I started this, but as always especially with this round, IF YOU CHAMBER THE ROUND either SHOOT IT OUT or EXJECT AND PULL THE BULLET. This is a bit overkill, but help prevent you from bullet setback.

ALSO AA#9 12-13 grains, will prevent bullet setback
You have had success, but since RCBS got the orignal die specs wrong, I can't support their instructions. The round headspaces on the small shoulder, RCBS says on the case mouth, that is wrong. If you shoot plated bullets, a slight bell will help keep them from gouging the bases. I have even collapsed case neck trying to seat w/o some slight bell. I would rather bell than chamfer, chamfer leaves less neck mat'l. for a good crimp. RCBS got it wrong IMO, Dillon dies are perfect, Lee & Redding also got it right, but are not carbide (which baffles me, just put the carbide sizer in from the 40 die).
"Given adequate penetration, a larger diameter bullet will have an edge in wounding effectiveness. It will damage a blood vessel the smaller projectile barely misses. The larger permanent cavity may lead to faster blood loss. Although such an edge clearly exists, its significance cannot be quantified".
