Had a very interesting thing happen at the range today. I'm getting final sight-in for my prairie dog hunt and with my most accurate load for 40 grain Vmax with H335 at 3400fps for my AR I was going to also bring my 50 grain Zmax load with Benchmark shooting 3435fps and their points of impact at 200yds was nearly identical. Close enough to not change the dial, under 1/2" higher and still centered left/right.
