so far, in the 177 disco, some of the most accurate pellets, are the lower priced ones. the crosman 7.9 hp, 7.9 pointed and the 10.5 domed. the discovery 10.5 hp all shoot very well. only have 10 yds to shoot in and all of them will make one hole groups at that range. neither the 177 or the 22 seem to like wad cutters or sharply pointed pellets. john
