6.5 Grendel V.S. 7.62x51 500yds & Beyond........ Questions......

[rwh]

I have a 28 inch grendel that can shoot a 130 gr berger at 2570 fps, and a 308 palma rifle that shoots a 155.5 gr berger at 2950 fps. I compared the ballistics with the calculator at berger bullets site. At 1000 yards the grendel drops 37.3 MOA. The 308 drops 30.1 MOA. However with a 10mph cross wind the grendel has 8.6 MOA of drift and the 308 has 8.7 MOA of drift. That seems fairly comparable. Note that I am shooting 155.5gr bullets at 1000 yards from a 308 purely for sport. There are better bullets for 308 that can trim a couple of MOA off of that wind drift. I don't worry about drop if I know the distance. Wind drift is what matters and I think the grendel is arguably comparable to a 308 shooting a palma load at 1000 yards.
