Reply To: FX Impact Velocity Data
FYI… I have found that with the ST barrels and jsb pellet combinations that higher speeds produce the best groupings. With .30 880-890ish, .25 880-920ish
.22 900-930ish I haven’t tested .177cal.
At the posted speeds groups were 0.5-1.0″ respectfully at 50&100yds.
My Impact loves polymags as well just to put it out there.
