I shoot a metric fuck ton of Hornady match ammo for the simple reason that it requires zero time to be ready to go to the range. Can I make better ammo at home? Slightly. But it takes all goddamn day.
I’ve got a wall full of trophies from local matches won with factory ammo. I don’t think it makes a difference for 90% of the people. Maybe more than that. I heard a guy on a podcast recently say something to the effect of “don’t shoot Hornady factory ammo, that stuff is trash”. The only people that make statements like that are trying to sell something.
