I am at the line, locked and cocked, ready to squeeze…..
I found two MP Molds that I am considering fro son’s AR .300 Blk.
This one IS the one I want, as I can also use it for several other specific rifles in my friend/ family circle. I’m just nervous, because it is a bunch of money, and if it will not work in AR Blk, then it’s original purpose is dead in the water. I’m concerned because it doesn’t mimick the profile of Lee 155 that does work in his rifle.
MP Bullet Mold - .308 / .300 Blk / 30-30 - 308 Hunt Hollow Point Gas Check - 4 Cavity Brass
Cast .312 cal. bullets – 154 grain hollow point or 159 grain solid
Or this one, that more resembles Lee 155, but MUCH lighter:
MP Bullet Mold - .308 / .300 Blackout - 311-410 Hollow Point - GAS CHECK - 2 Cavity Brass. solid 135gn., 124gn big round, 129 small round
Any advice, experience and constructive input is greatly appreciated.
