[QUOTE="jcann, post: 1488788, member: 37453"] I would need to achieve ~3,050 fps to make hits on a target at 910 yards with 5.5 Mils elevation. I’m shooting 65.8 grains of H1000 powder now, I don’t think I could get enough powder in the case to do that without blowing something up. We used the same chronograph (Magnetospeed) to recheck my sons 260 Rem. His rifle was shooting 2775 fps and the Shooter App displayed 24.4 moa for 910 yards. Dialed it on his Bushnell scope adjusted for wind and busted the 10” gong. My rifle constantly shoots at or almost this speed (2,920-2950 fps) depending on powder/bullet lot. The fact that we had first round hits with my sons .260 verifies the ballistic app seems to be working correctly. The only other variable is the Vortex internal adjustments. I guess when it’s my turn to shoot I’ll shoot my sons rifle. After the hunt I’ll run a box test and a tall target test on the Vortex. This will teach me not to buy a scope this close to hunting season. [/QUOTE]
