I have a friend who is trying to set up
a a Vari-x 5 on his S91 .504.
He is shooting 90 grains Pyro Select RS.
Zeroed at 100 yards and 23.75 low at 200 yards. MV at about 10’ from muzzle is 1257 (12 FPS ES) 300 yards, 97” low.
I’ve tried plugging those numbers into a b.c. Calculator and can’t get them to jive.
What am I doing wrong??? I was using Berger’s BC calculator. and everything I tried, came out to only about 80” low at 300 yards with the 23.75 at 200.
He’s trying to have turrets made and I’m at a loss on the BC.
I’ve tried from .22 to .19 (as low as Berger’s program would let me go) and am at a loss……
