Hornady 250gr HPBT Match
26" barrel
TBAC 338 Ultra
10 shots each
Unsuppressed - 2874fps, SD 32.7
Suppressed - 2895fps, SD 12
Two shots in the unsuppressed group were almost outliers (>2SD below average). Removing those, the 8 shot group is :
2888fps, 16.7SD
Meaning the suppressor makes less a difference on velocity than QC on Hornady's ammo.
