load for subsonic whisper
I just tested 4 different loads last weekend thru my 10.5 whisper.
220 gr smk
tp555 gas block subsonic position pistol position
gas port .115
Gemtech Sandstorm suppressor
ambient temp 32 deg
I had the same problem as you did with three different loads: extraction great, ejection great, reset the hammer but would not pick up and put a round back in the chamber. Pulled the trigger and the hammer would fall, but....
Loads that did not work:
AA 9 9.0 gr average velocity 1101
AA 9 8.7 gr average velocity 1022
H110 9.6 gr average velocity 1044
The load that worked and cycled perfectly:
AA 1680 11.7 gr average velocity 1018
email me if you would like complete data and information. I have each load on an excel spreadsheet.
I saw that someone posted a load for H322 somewhere, but cannot find that information. I figured that could be a good load cuz it makes a carbine work. Ok, strange, but, what the heck. Why not try it? Anybody have a load for 322?
