I color highlighted the same loads. Rounds were fired in the order by number. All rounds were fired over a prochrono digital at ~35 feet from the muzzle. The wind picked up from right to left for rounds 11 and 12.
Thoughts?

Nice post. I see fellas at the range that I'm a member at produce targets like that consistently using store purchased ammo all of the same weight and grain at 300 yds. So what does it really tell you?


Maybe they can't shoot for chit.... whistle


That may be true, but not necessarily. Without the ability to tune the ammo to thier guns they might get significant vertical dispersion. That's the whole point of the test, tune the load to the harmonics of the barrel for the least amount of vertical deflection. Wind, well that's up to the shooter wink
