I'm new to reloading and I have had a problem lately with a few bullets (2 out of 50) coming loose from the case as they are being fed into the chamber of my FNS-9. They will jam just as they enter the chamber and when you clear the jam the bullet, powder and case fall out separately. They appear to be together when they jam but fall apart as they tumble out. I'm shooting Speer CPRN nose bullets and using RCBS's 3 dies set. Not sure if I'm not crimping enough or if I'm expanding the case mouth to much. The OAL of my loads are where the manuals say I should be. When I look at the bullets that fall out I can see a slight ring around the CPRN from my taper crimp. The bullets get a small flat spot on the tip when I use the seating/crimping die so I would think the expansion and crimping settings I'm using are OK. The bullets that fall out measure .354. The Speer CPRN should be .355. Not sure if this is enough to cause the problem. Any and all help would be greatly appreciated.
