I just picked up a HTC310-225-RN-CE4 5 Cavity PB for 300 blk, and love it, what col have you guys been running, it seems like the bullet wants to be seated fairly deep. And how have you guys been crimping, i have a lee set of dies. I just got the mold broke in and use hitek and h110, and the gun is an ar15 with 16" barrel pistol gas. Any good starting point would be appreciated as this is my first time with semiauto and cast. This mold really seems like a winner.
You may not have to crimp I don't use that particular mould but do use several other I seat just deep enough to fit in the mag and size the nose to just slightly engrave the riflings. just make sure you can eject the round if need be without pulling the bullet.
fitz, i made a split cast today and if i load the rounds to 2.26 they are about 10 thousands off the lands, any powder recommendations i have heard 1680 is ideal for subs.
