Another guilded bullet question.

[elkman06]

When loading Berrys/Rainer coated bullets, does anyone else find they have to crimp their pistol rounds w/ more force than say a hard copper jacketed round?
I keep getting length issues w/ my semi autos,,gotta be the bullets nudging forward..Thoughts? I have had no issues w/ jacketed bullets.

secured

Case neck tension secures the bullet in 'auto' cartridges; the crimp removes any residual flare, and ever-so-gently presses the case mouth into the bullet.

In revolvers, the crimp (from the superior Redding Profile Crimp die) can aid in keeping a bullet from moving forward under recoil (inertia.....), but case neck tension is still the mechanism that secures the bullet.

Too much crimp on plated bullets may seperate the copper from the lead core, which is radically detrimental to accuracy.

Bullet diameter? (don't guess; use a ten-thou mike)
