We're getting a bit off-topic, talking about retained energy and killing power at 40 yards, when the topic is lead at 20-25 yards, skeet distances.
A crossing target from station 4(skeet) requires 41.23" of lead, when the shot leaves the muzzle @ 1100 fps. Starting @ 1150 fps, lead is 39.44". 1200 fps requires 37.80" and 1250 fps needs 36.28" of lead. 150 fps difference in MV makes a difference of less than 5" in the lead on a skeet hard crosser.
My questions are: Are the quoted amounts of lead for a dead gun, sustained lead, or swing-through method? Would it make a difference? If so, how much? To keep it as simple as possible, let's assume we're only discussing 1150 fps.
