So I was shooting through my buddies chronograph with reloads and I was getting a muzzle velocity average of 2760 today I finally had time to shoot alittle further I typed in all my info into the shooter app and set up the target at 450 yards. I read the app and adjusted my scope where it told me to and I was shooting about 3 feet low. I had to adjust my velocity on the app all the way down to 2275 to be hitting where I was aiming. I know the calculator isn’t perfect but that seems way off. My buddy is shooting the same gun, same reloads, same scope, same data entered in the same app and he has his velocity set at 2650 and is hitting where it needs to be. I’m lost.
