Ron has a habit of being facetious, to the point of being provocative, but I don't think I would ever say he is "misinforming" anyone. Thank you Functor; I see 'you get it'.
I guess that means no? Correctamundo, Sonny. Accuracy improvements are undoubtedly possible from weighing/measuring/sorting/washing/lubing pellets. It's simply a matter of how much return, at what cost.
I just supplied you with the math that proves weighing pellets will shave TENTHS off your group size when shooting at 100 or more yards…and HUNDREDTHS at 50 or less…please don't misinform people by claiming weighing pellets only shaves 'thousandths' off your group size… I misinformed no-one Ack; and would venture to say my statements at least as accurate as your math puzzle, as proven by my own actual testing.
In as-scientific-as-I'm-able testing at 100 yards with my extremely-accurate .25 Cricket, I shot three consecutive five-shot groups with JSB Exact King Heavy (33.95 grain) pellets varying .9 grain against three consecutive five-shot groups with those pellets sorted to within .1 grain. I couldn't believe the .9 grain pellets shot tighter groups, so repeated the test with the same results. Still in disbelief, I then retested using ten-shot groups; and again the inconsistent-weight pellets outshot the consistent pellets! Hard to believe, but that's reality.
Suffice to say I've always preferred putting faith in personal experience(s), and this accuracy experiment blew hell out of my faith in theory, conjecture, and/or others' experiences.
FWIW, now convinced weight-consistency is almost a non-issue (within reasonable limits, of course), I believe head-size consistency more important than weight consistency to the accuracy equation. "Your results may differ"; I'd love to hear details of your testing.
