I think I answerd correctly

[A320PYLT]

I was asked if one zero's his scope on the Grendel at 25 yards where will it hit if he shot at 100 yards. Well since the projectile is still traveling upward it should hit 1.5in high or there about. I think thats correct.

Yup but it depends on a few things. The distance of the sights above the barrel, MV, weight of projectile etc. Please see below the data I put in is almost at the bottom.

Actually depending on your scope mount You might still be a minus. By the Vortex LRBC Balistic data base you will be at -.8 at 20 yds with a 100 yd zero scope height @ 1.5 )

I would not think that it would be dropping by 100yrds

With the AR platform the centerline of most scopes are 2.4 to 2.7 in above the bore. Therefore a good rule of thumb with an AR is to be about -1.5 in low at 25 yds to be dead on at 100. If you sight dead on at 25 you will be 5 to 6 in high at 100.

I' not saying tha bullet is dropping before 100 yds (with 100 yd zero) but bullet is still under your line of sight. The bullet doesn't start dropping till after 100 yds (on 100 yrd zero)
