I didn't want to hijack someone's thread so,
has anyone experimented with lighter grain weight bullets in the M1 30 carbine with a goal of higher velocities & accuracy at longer ranges? I see Speer & a few others make 100 gr. spire point jacketed .308 bullets. Don't see much out there for boolit molds made to cast sub 110 gr boolits.
Maybe a truncated cone style projectile? Or a sabot round?
Remington used to make a 30-30 cartridge with a 55 gr .223 bullet in a sabot.
I'm guessing getting the right COL while having enough room for a adequate powder charge would be the biggest problem.
Before anyone suggests it, I don't want to acquire a 300 BO.
