What is the difference in velocity at 50 yards for #4 steel @ muzzle velocity of 1,500 fps vs muzzle velocity of 1,250 fps? How about the same numbers for lead?
Back to the topic, I would still like information on the above questions.
cpa, here's what I find in Taylor's "Shotshells & Ballistics": 1500 fps MV, #4 steel: 590 fps @ 50 yds. 1250 fps MV, 536 fps @ 50 yds.
Same book, #4 lead: Can't give you 1500 fps. 1400 is the fastest listed: 710 fps @ 50 yds. 1250 MV: 665 fps @ 50 yds.
Comparing with Miller's post, the charts in this book give slightly slower down range velocities.
Stan, comparing 8's @ 60 yds, MV for the 1135 fps load is 438 fps; for the 1330 fps load, 477 fps. The difference for 4's @60 yds, 1330 fps vs 1145 fps: 618 vs 569.
