Does anyone have a pet load, powder or starting point for a .223 load with 75-77 grain bullets
I use 24.0 grs of Varget out of my AR with 77 grs SMK's, it shoots very well for me, as does the same charge with RL-15
Are you getting any more velocity with RL 15? I just bought a pound to try. I'm shooting a WOA upper with a 7 twist.
My ar load for a nato chambered dpms
75 grain priv. partizan hpbt
cci 450(or mil-spec)
max ar mag length
lc 5.56 brass (or fed 223)
2800 fps in a 20" ar-- chrono'd
loaded with standard rcbs dies and no crimp this will do 1.5" at 100 yards with the factory peep for 5 shots. In a bolt it would probably be 1/2 moa as I wasn't even bagged up but had my 30 round mag rammed into the hard rubber surface on the local bench.
75 gr A-Max
My best right now is:
CCI BR 2 primers
That load gets me <.25 MOA if i do my part.
These loads are near max if not on max.....no problems in my rifle though
I'm not sure of the velocity I'm getting, I've never chronographed them. I shoot a White Oak as well, mine has a 1-7" Krieger on it. This is a standard load for several High Master shooters I know and for myself. It has shot extremely well for me out of four rifles. I'd guess 2,600 fps though for velocity.
I have been using the Hornady 75gr BTHP in my Stag 6H AR-15 with very good results - .5" at 100 yards. Chronographed at 2800fps with no pressures signs using the load below.
