Goin to a shoot where the targets are at 75 yards. What would be the difference UP from 50 yd or DOWN from 100 yd setting to make it "on" at 75 yards?

Any diff between HS and SV ? I like the groups of the SV much better.

Standard Velocity LR solid would have about an 8" drop from 50 to 100 yards. That is what I raise my Remington 541X when going from 50 to 100 and it is on target. Byron

I shoot CCI standard velocity and it also drops about 8 inches at 100yds in the summer. In the winter it drops even more:confused: I think it has to do with the density of the air, and cold powder not being as high pressure or something:confused:

Most 40 grain bullets have ballistic coefficients between 0.115 and 0.150. The most common muzzle velocity in my ammo library for 40 grainers is 1255fps. Take that to the Norma ballistics page (http://www.norma.cc/htm_files/javapagee.htm) and play with the sliders. Be sure you do not ignore the height of sightline slider.

Post or PM the load you use and, if it is in the ammo library I have, I'll post the B.C. and muzzle velocity.

Of course, calculated performance is only a starting point for calibrating your particular system.

My Ruger 10/22 with a scope shoots virtually flat out to 75 yards shooting the Federal Bulk Pack Hollowpoints. It's dead on at 25 yards, about 1/2" high at 50 yards and 1" to 1 1/2" low at 75 yards. After 75 yards it begins to drop off rapidly.

Another thing, the .22's don't buck wind very well. So a small breeze, and the bullet drop might be even faster.. Just FYI..
