I got a 177 HW97K a couple of weeks ago and tried the usual pellets, JSB, AA, H&N and the crosman HP in the tin container. They all shot pretty good with the JSB 8.4 doing the best. I was in my shop and ran across some crosman destroyers 7.6 gr and just tried them to see how they performed. Incredibly, they performed better than any of the pellets at 25 & 35 yards. I'm going have to run to Wally World and try to find more.
