223 Ackley Improved

Initial pressure test and load sample for a new criterion 16” 223 ai.

Formed starline brass
Cci 450s
53 vmax
Benchmark, xterminator, and tac powders.

Pretty impressed with the velocities got to 3150-3300 before noticing pressure depending on the powder.

I shot the same loads back to back with my 22” 223ai and saw a 200-250fps increase with the longer barrel.

Cool deal. That thing shoots so well, it predicts the future.
