Loading 338 arc for an ar platform. Started out using 225gr SST super and subsonic. 16” Shaw barrel 1-8 twist pistol gas alien gear adjustable gas block. Loads were all using lilgun. Supers cycled fine, subs were slow (700fps) and cycled without having to adjust gas.
Switched to a 10” barrel .Gas wide open.
Nothing works.
Switched to H110 and 300 gr T-Rex maker bullets.
Subs were going 1090 no cycle but stable.
Added can, still no cycle(25 fps increase)
Next on the list is AA1680 to try tomorrow.
If this doesn’t work the Shaw goes back on.
