Hi all
I've been trying out some different .22LR in my CZ 457 LRP. I'm curious about subsonic ammo.
CCI 40gr subsonic, three shots: 1138 fps, 1116 fp, 1136fps
Eley 40gr subsonic, three shots: 1118 fps, 1110 fps, 1106 fps
Only the RWS are providing to be subsonic: 1075, 1047, 1047, 1063, 1076.
Is this normal? I know barrel length, altitude, temperature etc all influence the velocity, but these seem consistently inconsistent!
Thoughts?
Jim
