Re: 308 components
Mostly RL15 and IMR4064 for the 168s
little Varget
I get better V out of RL-15, needed in the 20" & 21" barrels. I've also had some issues with warm loads living in WI and shooting them in the TX summer, especially with FGMM brass when the primer pocket gets questionable. Rl-15 is a double-base powder, Varget single.
Nosler CC 168s (cheaper short-range loads)
Sierra 175SMK
Mostly Hornady 178AMAX
3 1:10 barrels, one 1:12
The lapua 155s are probably a better choice at range, I have'nt switched over to them...yet
GM210M primer
little CCBR2 in the past
FGMM reuse and Win Brass
Pretty basic and popular components.
