Other And the Cometa Fenix 400 Premier USC likes ...

Shot for groups at 12 yards rest indoors with these three pellets and the Cometa clearly prefers the Air Arms Diabolo Field 8.4s. After I shot with these three pellets, I tried two more targets with the H&N Field Target Trophy 8.64s and the results were similar to the 9.57s -- maybe a bit more accurate. Although all are supposed to be 4.52, the latter were the tightest fit and the JSBs were the loosest.
I knew the Cometa was capable of one-hole groups at this distance.
One thing that surprised me was the differing points of impact of the three pellets.

Tried four flavors again, and the Fenix USC Premier Star can't seem to decide if it likes the H&N Field Target Trophy 8.64s or the AA Diabolo Field 8.4s best. All are labeled 4.52, but the H&Ns are noticeably tighter in the breech than the others. From largest to smallest groups this afternoon:
