I'm confused.
I have a load for my 45 Colt carbine that produces 1620fps with a 265g bullet and have my rifle zeroed for that load.
I decided to load some plinker rounds using the same bullet that produces 1100fps.
The lower velocity rounds impact 4" HIGHER at 50 yards than the higher velocity rounds.
I understand that the lower velocity bullet spends more time in the barrel and is therefore more effected by muzzle climb due to recoil, but at the same time the recoil from the higher velocity round is greater producing a higher rate of muzzle climb at least partially negating the time the bullet spent in the barrel.
Also a factor is the time the round takes to impact the target. Since gravity begins to affect the bullet the instant it leaves the barrel, the less time it takes for the bullet to impact the target, the less time gravity has to affect the bullet so less drop.
It still seems backwards that the lower velocity round impact 4" HIGHER than the higher velocity round using the same bullet.
