Anybody have chrony #'s for a 2240 with 24" 1760 barrel (ie 1740)? with stock internals? Only mods being steel breech and 24 inch .177 barrel. Thanks.
(already did the obligatory search, all the fps reports i was able to find were either from shorter barrels or from modded-to-the-teeth, weighs-half-as-much-as-a-normal-valve-due-to-certain-areas-being-ground-off-valves or a combo of the two)

1740/1760

I found this thread...

http://www.network54.com/Forum/275684/thread/1223862694/Just+ordered+a+2400KT+w+-177+24+inch+barell+and+long+steel+breech

One guy says his stock 2260 with a 1760 barrel is shooting about 650 fps. The 2240 and the 2260 have the same valve and both run off one 12 gram, so the pwerplants are basically the same.

I plink, therefore I am.
