100 yards is "a long way" with .45ACP. Some factory 230gr hardball rounds made the target with about 3 foot holdover out of my series 70 Gold Cup, some skipped in from 6 feet in front of the berm at the same holdover. Dropping bullet weight to 200 grains and increasing velocity about 100FPS allowed much less Kentucky windage and much more uniform patterns (can't quite call them groups once they exceed dinner plate size). Don't know what the BC is of either projectile but I bet it is miserable, and I suspect at least in this case means more for long range accuracy than any variation in muzzle velocity.
