red squirrels make a mess around my families houses and seem to multiply like mad, so i've been looking for a quiet way to get rid of them. I don't have a pellet gun and 22's seem to ricochet more than id like. so today I tried loading Crossman 14.3gr 22 cal pellets in a .222rem. pellets are loose in a fired case so I sized them and pellets make for a tight enough slip fit, pushed in flush against the table. just a primer gave 375 fps and similar sound to dry firing. 0.5 titegroup gave 550 fps and similar sound to a pump bb gun. 0.7 650fps. 1.0gr 830fps and sounds like maybe 22 short without a sonic crack. im a bit worried about pellet skirts on the heavier loads and slightly more noise than I wanted for around houses. I think around 600fps in 22cal is good enough for squirrels right? also they don't seem to push primers out so im not sure id need to drill the flash hole. all in all im really happy with the setup, its cheaper than buying .22 cb shorts which are 10 dollars a box now, and easy to make for anyone with a low capacity 22 cal rifle.
