18" BHW 264 lbc.
Ran a ladder with 123 Amax and 8208. 26.4 to 28.5 gr. in.3 gr increments. 2.252 coal hornady brass, CCI 41
Velocity topped out at 2509 at 28.2 gr. at 28.5 velocity was the same.
There was 2 distinct nodes. One around 27 gr and the other close to max.
All 8 rounds were in about 1.5". I loaded several at 28 gr and got this. Ouch.
Really surprised. At this point I decided to start changing the coal as I really wanted to be closer to 2500 fps.
28 gr. 2.266 coal
28 gr 2.283
28 gr 2.295. This was max comfortable length with the asc mag. At 2.3 the tips were touching tge inside of the mag.
