I load 26 calibers. I won't tell you how many guns. I shoot a lot during the year, but not as much as I like because of my affliction....I have to go to work.....LOL.
I load in the Winter and into the Spring. By July 4th I don't have time to reload since the boat is in the water so they all sit until after Deer season. After Cristmas I start reloading again and usually have about 3000 rounds ready to go. I usually knock them off in about a week, working evenings and one Saturday. In a Saturday I can reload 1000, not working too hard.
I have 4 single stage presses, each set up for a different die.
