I'm not sure if Chairgun number are accurate but for me I show 12 lbs/ft at 50 yards using the Crosman and 14.7 with the JSB. If you can tolerate the occasional flier, the cheap Walmart tins are cheap shooting.
Tater, did you every get rid of that fine looking cat? Had a bunch of very similar looking ones here last spring. Emphasis on "Had". LOLKnife
