I found that I did smaller runs of ______ before I had a good array of "pet" loads. The more of these "pet" loads I nail down, the larger my output is when I sit down to make them. I will be making a particular run of something and say, "Wow, I'm getting tired of handling these small 9mm slugs and I'd like to make some .45" back like I used to do... but it doesn't make much sense. Afterall, the powder measure is full and set with the perfect charge that I need for my favorite 9mm load. And for sure... I know I need a lot of that 9mm ammo.
So at last session, I finally stopped making 9mm when I got to a thousand of them. And that's semi-progressive, of course, with brass I had prepped 3 weeks back.
One problem that I think
that I have is before a range day when I'm trying to figure out which handguns will be chosen for the trip... is that I look at the ammo cabinet and the tallest stacks often get the call. I worry that sometimes I take more ammo than I ought to, and I'm compelled to burn through it simply because I have it. I wouldn't go so far as to say that it's wasted shooting (I don't just fling 'em down range to rid myself of them!) but I do end up going through more ammo than maybe my budget would like.
I tell you, if some evil force came down and made it impossible for me to handload, I just don't know how much center fire shooting I'd continue to do. Handloading is such a massive factor in how & what I shoot.
