The first time shooting my 16" Grendel, he cleaned my poppers at 300m, went to 400m and hit everything 1st-round, then made a 1st-round hit at 500m on a steel IPSC target, with the impact dead center for windage.I'm not sure how much value to place on your BIL story. It appears to me that riflemen don't use drop charts, let alone have spotters with high-power scopes.
He used the drop chart I had generated for it with Brian Litz's Berger Ballistics program, and me on the spotting scope giving him his wind calls...
Quote:...a 6.5 Grendel will allow entry-level soldiers to miss closer than they would with a 5.56 NATO carbine...Where is the test data to support this claim? The "I'm hit!" video I posted shows what seems typical for how soldiers shoot in combat. Judging by that, I cannot see how they would likely "miss closer" with 6.5mm than with 5.56mm.
