I had not tried these pellets before so I picked up a couple of tins at Wally World the other day. 500 count tins were less $6.00. I finally got a chance to send a few down range yesterday afternoon. I must say that I am highly impressed with these pellets. All seem to fit my Crosman F4 perfectly. Had to do a little tweaking to my scope but have it dialed in pretty good. Shooting nickel size groups at 30 yards. Going to be using this rifle for squirrel hunting since .22 rim fire cartridges are almost impossible to find and when you do find them they are outrageously priced.
