Ran a comprehensive pellet test with my AA S510 XS in the summer.
Tested a lot of pellets & at various power levels.The results were very revealing even @ 20yds & some shocking @ 40yds.
Tried H&N Slugs,both sizes in the test packs.Only one i could get to group was .218 27gr@ 27ft/lb,the rest was looking like a 12 gauge spread on the board.
Just as in centrefires, you need to find what your rifle likes to be fed.
