For most of the past 20-some years, I've kept my batches of rifle ammo small-- 20-25 rounds. This was because it was the amount I could do in an hour or so of reloading. When I was working and raising a family, that was usually just right.
For pistol ammunition, I generally loaded 50 rounds at a time.
The first big change was about 5 years ago when I started casting pistol bullets. I was doing more loading and more shooting, and I needed to do bigger batches. I invested in a Hornady LNL Auto-Progressive. At that point, a loading session started yielding 200 to 500 rounds.
Most recently, I've decided to reformulate some of the family's top loads and do large runs. My sons each got 50 rounds of their best 30-06 deer ammo. I did 50 rounds of my new 150 grain 30-06 load. All told, I cranked out 150 rounds, and did it all as one batch, with minor changes along the way.
