Things I liked:These are very nicely formed, do not vary greatly in weight or diameter and are clean. I get very good to excellent accuracy from my Crosman 2100 and Model 113 CO2 rifle. Things I would have changed:As usual, a screw-on lid. What others should know:I do not often use the .177 cal. on squirrels as I prefer the superior effectiveness of the .22. However, my Crosman 113 is so very accurate with these that at 20 yards and under, the shot is always precisely able to be placed and the squirrels are dropped instantly by head shots. This pellet also retains velocity very well for a pointed pellet (believe it or not, pointed pellets generally do poorly compared to round nosed designs). This is a very good investment.
