Fellers, I need to be schooled on a couple points on the 300 BO. Please.
I ordered a 10.5'', 1-8 twist, pistol gas system AR barreled upper in 300 BO. Which I have zero experience, in this caliber. I also ordered the Lee 3 die set. Have 180 1X cases incoming too.
I want to shoot 150-175 grain, CAST bullets. Already own the molds. The 175 throws, GC and PB bullets, 150's are PB. Can I get them going 1200 to 1700-ish with 2400 or similar powder? Do I have unrealistic expectations? Do I need exotic powders?
Will they run going that slow? Do i need a heavier bullet? I am NOT apposed to heavy bullets.
Do I need the "special" 300 BO magazines?
Many thanks, in advance. Randy.
