That's a great find! It'lll be great for hunting!
I like the JSB 13.73gr. They were the most accurate from the Beeman Crow Magnum.
Find some pellets it loves and stock up. It's not common enough to get really good pellets at the local sporting good stores.
I bought a pellet sampler of .20cal pellets from Straight Shooters and several pellets were discontinued by the time I ordered some tins...
Fortunatly the JSBs it likes best were still available but the Crosman Premier was not.

You will remember a curve of your wagon track in the grass of the plain like the features of a friend."
