I bought a variety of 22cal slugs a couple of weeks ago for the fun of seeing how well they perform out of my 23 year old AAS410. I hoped for some 1 hole groups. Though they performed decently at 25 yards, the 16gr JSB’s still beat them. The weights of the slugs ranged from 20gr to 23gr as I don’t think a 30ft/lb gun can launch heavier pellets fast enough to make shooting out to 50yds feasible.
