My issue with fixed rotors is that the chart doesn't exactly match the real world results. The one I tried had a 0.5gr difference than what I wanted. So I went back to the adj rotor method.
Now, take this with a grain of salt as I have only tried one powder and one rotor, but it was enough for me to send it back. I bet if I loaded for more than one pistol, I'd be singing a different tune.
Relative to that, circumstances infuse relativity too.
There is definitely a compromise involved, but I've found with the faster pistol powders, it generally doesn't make a lot of difference unless I'm really fine-tuning for loads beyond 50 yards. I use my Uniflow 99.9% of the time, even for such loads, but once I've established my nominal loads for a project I'm working on, I will be looking for a way to throw the optimal charges with something fixed.
This too is for a kit - a last-ditch/hold-out/bug-in kit, which would keep me shooting, at least to some drgree, regardless of the general, or my personal economic situation. It won't produce 500-yard prairie-dog loads, elk or brown bear loads, but loads with which I can defend myself, my property (destructive vermin/varmints) or take advantage of a local hunting opportunity. More important, just being able to shoot for the sake of being able to shoot - a combination of workable compromises to achieve some level of utility between the extremes.
I rarely use my old bushing-type dispenser, but following Ben's lead, I can see a useful place for it in such a kit.
Dippers? Yeah, I suppose, but I'm not planning "bugging out," "heading to the hills on foot" or living in the woods in a debris hut. Any place I go, I'll be pushing a wheel chair. If my wife can't go there, I don't go there. If the house were burning and I couldn't get her out, I guess we'd both burn up, but just as well t hen. However, should circumstances force us out of our comfy home and into something smaller, with no "extra rooms" or a shop, I want a kit I can easily toss into the back of the Jeep or trailer and use in tighter quarters. That's not the PLAN, but I'm planning for it anyway. If I have to sell or abandon everything else, this kit, one rifle and one revolver will be the MINIMUM I carry (in a vehicle) away from it.
I've handloaded like this before, while in the Army and living in apartments. Everything (to include a 3-hole LEE turret press) fit into a plywood box I had built for my two-burner Coleman camp stove. It fit on the left/rear seat-floor of a two-door Toyota Tercel and was with me even as I traveled between assignments. It's slower, but sort of liberating at the same time.
There are seemingly boundless sets of circumstances around which to assemble such a collection and seemingly boundless "right ways" to do it. I actually was able to fit my Uniflow into that plywood box, with 2# of powder, 1k primers and 500 cast bullets too. I'm looking to reduce weight and bulk this time around. Einstein was onto something regarding relativity - GRAVITY is relative to one's AGE. Sh....TUFF weighs more now than it did when I was nineteen.
