Another Crimp Question

**texas 48** · 03-11-2010, 21:11

I have loaded a number of 165MG with starline brass with a 9.7gr charge of Power pistol. The crimp is .419 vs standard .421. Is this way over crimped? or is .002 not a big deal.
Thanks

As for as pressures, it would matter more with a fast burning powder,right? A slow powder might need to be crimped more with a light for caliber bullet as long as doesnt effect the headspace.
