I make some pellets, that have terrific penetration, I'll take an H&N Crow Magnum and add a tiny drop of super glue, and place a Daisy BB on top, when the glues dry they're inseparable.They come out to around 23gr, and are extremely accurate, the smaller bb is centered in the crow magnum so it doesn't touch the ******s rifling. Impact, is terrific with the bb being pushed straight down, and the sides folding down, On the occasion when I do see them flying through the scope the trajectory is extremely flat, and they fly pretty fast too, a while back I used them paired with a modded QB 78D, and made an incredible 50 yd shot that put a Jack Rabbit on the table that night,,I always keep a good supply on hand, and it only takes a few minutes to make a hundred or so. Cheer's, Andy.
