Luckily, all of my PCPs shoot Crosman pellets well.
My Urban loves 14.3 Crosman Premier Hollow Points . My Liberty in .177 shoots 7.9 Crosman Hollow Points lights out. And my Walther Dominator in .177 shoots 10.5gr Crosman Premier Domes in one jagged hole at 25 yards.
I get all of these pellets from Walmart with the exception of the 10.5gr, which I order from Amazon. Even with Amazon's subpar packaging, the Crosman pellets seem to be arrive relatively unscathed. I've had good luck with H&N pellets from Amazon too. JSB..not so much, since the lead they use is much softer.
So yeah...JSB pellets are more accurate in my guns, but not enough to warrant the difference in price while I'm only punching paper in the backyard. Once hunting season come back around, I'll be ordering more quality pellets, no doubt. But for now, I'm saving a small fortune by using readily available pellets.
