I have a new Fx Panthers 700mm 22 cal. This is new experience but from powder shooting from my past boat-tail must have need most accurate... so ATP 22 king 40gr slugs are a no brainer for what is the best for long-range slugs. I have been looking for best tune for your 22 40gr kings. So far from my limited shooting (200 slugs shot) that 890-905 fps (72-74 ft/lbs) seems best and to push harder (increasing reg. pressure and or hammer hit) are both less accurate and less efficient with air. It seems to be a glass ceiling to ATP king slugs. Just checking to see if this "Glass Ceiling" is similar to your experiences?
My Anschutz and CZ 457 22lr rifles push a 22lr 40 gr at 1040-1050 bullet (100 ft/lbs). It maybe impossible to reach these 22lr energy levels (ft/lbs joules) with Fx Panthera and slugs. Just asking important questions for expectations.
