Would you believe 1024 fps in 19-20 pumps with 7.9g pell and MK 177 power...

[K.O.]

I did not at first...

BUT
yep I hogged the valve out to .242 C.I. just to see what I could get and WOW...

so yes it is looking good to get 20+ fpe as a 1322WT when the parts get here... just maybe 24+ fpe with 14.3g pellets going 875-900 fps

holy phoo-phoo !

K.O.,
You never cease to amaze me with your ingenuity. I couldn't wait to see the finished MK177. Please please post all the technical data and pic. Thanks,

my 24" .22 barrel got lost by ups but another is on the way...

so it will be .177 first...

also I think  MK1377 or MK1322, MK1325

is better than 13xxWT whatchya  think...
