As I uderstand it, the Blackout is better for the 220 and 240gr sub loads, were as the Whisper's shorter throat is better suited for 125 gr. super sonics...
So since Im currently building an AR with one of Tp555'S .300/.221 barrels, I was thinking about building a bolt gun for subs later this year.
My question is, can I get away with using the Blackout dies for both? Or will there be issues with the throat length and the crimping? Im asking cause I have yet to buy my dies and will be needing to start some loads up here in a few weeks hopefully.
