Some basic math says otherwise, to shoot 500 rounds in a day you would be pulling a trigger on a rifle every minute for 8 hours straight. That's figuring no time for eating, cleaning rifles, getting ammo out,getting a drink, or anything else for that matter. If you really do shoot that much more power to you but that's not common by any stretch of the imagination. I liken your statement to the guy that posts up about every one of his rifles shooting 1/4" groups all day long. Sure there are guys that can do it but it isn't happening for everyone. By the way if you have enough money to build all those rifles and buy the componets for all that ammo why can't you make a small contribution to the forum and become a site supporter?
