Is anyone using this powder and have a good load with 55 gr Hornady sp's and fmjbt's ?
PSA 16" CHF CL 1/7 Midlength
55gr Hornady FMJ-BT W/Cannelure
C.O.A.L: 2.220” no crimp
Primer: CCI #41 SRMP
Powder: 25.7gr Alliant AR-Comp
I used a drop tube when working up this load, this powder really fills he cases.
I was able to get a 5 shot group just under 1moa with this load, with under .5" vertical spread.
Sorry, no chrono yet. :(
