JSB Field Target 16.0 grain and Straton 16.0 grian .22 pellets work OK in my S&W 77A, but the pellet that shoots the best in this rifle is the Beeman Kodiak 21.1 grain. This rifle will shoot the lighter pellets, like the RWS Hobby 11.9 grain pellets OK with 5 pumps, but sends them all over the paper at 10 pumps.
Other than the rifle itself, the best pellet buy that I ever made was the Straight Shooters 22 Caliber sampler pack. I think that it came with 25 each of 18 different styles, from 5 different brands (Beeman, Crosman, JSB, Lazapell, and RWS). A cheaper way to narrow down what does, or doesn't, work in your rifle.
