I started casting & reloading as a kid - probably around age 8 or 9. Pa had an ole Pacific single stage, a small casting pot and a GI one burner stove to use with it. Didn't have any extra money to purchase anything else and just purchasing primers and bullseye powder for the 38 special was tough enough. Don't remember the powder used for the 30-30 or 30-06 but didn't have much of that either.
Many years later I started shooting 2700 and there's no damn way you can make enough ammunition on a single stage to keep up with the volume of shooting needed to move up in the classifications and shoot matches once a week. I suppose you could if you had someone load all day long, a couple days a week for your week's ammo supply. Shot between 100 and 250 rounds a day, six days a week and on Sundays shot 270 rounds at the match - 180 rounds 45 ACP and 90 rounds 22lr. Never practiced much with the 22lr, as it was the most expensive to shoot back then compared to our reloads in 45 ACP and 38 Special and when we did it was at 50 yards - actually, 95% of our practice shooting was at 50 yards. Our handloads shot every bit as good as the ole Western Super-Match mid-range ammunition that the Service Teams shot back then - they always beat hell out of us, as they were better shooters. But they always gave us their empties to reload and sometimes several loaded boxes of that high priced Super-Match. We loved to see that 8th Army Armorer's Truck come rolling in with 2 or 3 top gunsmiths on their way to a major competition on the left coast - Great bunch of guys and most of the shooting team were members of the 2600 Club and back in the late 60's, that was saying a lot.
I still load on a progressive - started with a Starr Universal and now throw with a Hornady LnL.
