I usually shoot anywhere from around 50-80 rounds a week out of my 4 calibers, 222, had my 220 swift, 25-06, now a 270 win, and lastly my 300 rum. I like to stay on top of my game with all my calibers, so I shoot them all at least once to twice a week, putting anywehre from 10-20 shells downrange of each caliber, usually 300 and 525 yards.
