Hey Hunter, just went through this. I bought one at Dick's sporting goods and it chronied under 400 fps using 15.9gr jsb's, which were its favorite pellets. 14.3 crosmans did about 450fps. I modded/ported my valve and added a steel breech. Had to notch the hammer to clear the new steel breech screw. Added a heavier hammer spring and my 15.9's did 460fps on 10 pumps. It was pretty accurate and I didn't hesitate to try it on a young gray squirrel who was digging in my garden. Tried a 20 yard headshot and stunned him, then he took off with my following, pumping madly and repeatedly shooting him to try to humanely put him down. It reminded me exactly of my mispent youth, stinging squirrels in my neighborhoods trees with my very accurate but woefully underpowed daisy 99 champion. I was only about 8 or 9 then and didn't know better, now though, made me feel terrible. Truly at that moment I lost interest in the gun, cool as it was, and sold it online. Surprisingly, or maybe not, my bestest squirrel sniper is a hatsan .177 breakbarrel rifle thats only throwing 7.9gr pellets at about 750 fps. Not a lot more ftlbs of energy but I agree with your statement about the smaller calibers penetrating abilities giving it the nod. With headshots it drops them with hardly a quiver. I did use the 1322 on one awesome hunt. I shot 4 or 5 carpenter boring bees on the wing as they ate my sheds eaves.:-) big fun and an accurate gun. Not a good squirreler though imho. Jeff
