What is the highest fps you can expect to get out modded 1377?
Airforce Condor .25
1377 modded with 24"barrel
Daisy 880

1377x

depend on the gun,mods and how many pumps
it does reach a limit to where the pumping doesnt help
lets say 50 pumps gets you 800fps 60 pumps gets you 820 imo the extra 10 pumps dont help any
when i was shooting beeman kodiaks .22 21.12gr out of my converted 1377 to .22 i reached 662fps(20fpe) at 25 or 30 pumps i'll have to go back and get the recorded numbers anything after 25 or 30 pumps wasnt worth the effort just a few extra fps but still 20fpe maybe 10fps more maxit was maxed out hope this is not confusing.my gun pretty much maxed out at 20fpe with a 14.5" barrel never tried a 24" or any other sized barrel it could go over 20fpe in theory
closed mouths dont get fed
