I'm looking for a good load for 180gr bullets for a new 700 with 26" barrel. Range 300m-900m.
I was hoping to receive special brass, but right now I have on-hand;
-500x180gr Sierra matchking HPBT
-once-fired American Eagle .308 brass.
-CCI primers
-a lot of surplus military flake propellant with burn rate near IMR4064
I've got a store credit I'd like to spend at a local gunshop, so it's no problem changing any components. Though I'd like to use the bullets up.
Modern Reloading recommends 385. grains / 2.85 CC of 4064 to produce 2323 fps. With surplus powder, being extra careful, it would be prudent to use the lower of the two measurements if they do not correlate? Or if they don't correlate should the whole notion be reconsidered?
