...my modified 850 .177 Magnum...son was watching hits on target for me...20 yards...wuz fiddling with a new scope...
Practice,practice....this rifle (CO2) is very accurate and now shoots 810 FPS...stock was 760....new hammer spring/porting valves has made big difference especially shooting in 95 f weather...no more valve locking at those temps...stronger hammer spring fixed that...Also fitted a 9oz paint ball tank...get almost 500 shoots vice 170 on the AS can...helps on the power side,as well....
