looked pretty good. And I decided to get one, but didn't want to carry it around through the show. Then, in the rush at the end of the day I forgot about them(shut up, Og).
Happily, they usually have an ad in Handloader magazine and I ran across it, and ordered one. That was more than a year ago; I decided to give it a good try(thinking "Dammit, this better work as well as I hope!") before I said anything about it. And then tried it out, and did other things, and I kind of forgot to write about it...
Ahem. Where this thing really comes in is loading rifle cartridges using stick powders like IMR4895; these powders don't go through a standard-type measure very well, they tend to cut granules among other things. So the usual method is to dump a load that's a bit light into the powder scale pan, then trickle in a bit more to bring it up to weight. Which is about as delightful and engrossing a task as you imagine*, especially if you're loading a bunch of cartridges. Instead of a rotating drum this thing has a powder chamber that slides up into the body, and a set of tubes of different lengths that fit into the bottom. Look at the chart, figure which tube you want for the powder/charge you're after, stick it in(held by friction from an o-ring), add powder. It comes with a funnel that has a brass dome in the center:
The standard set comes with the measure, five charge tubes and the funnel, which also comes with several ends to fit different cartridges.
I've loaded a few hundred rounds so far with it, and here's the one thing you really have to do: be consistent in how you use it. Very consistent. If you move it up and down slowly, that's fine; if you move it quickly, that's fine too. BUT YOU HAVE TO DO IT THE SAME WAY EACH TIME, or you WILL get variance in the charge. Not a lot, but enough to be a problem for accuracy.
I've been using it for 8x57, .30-06 and .303, more for the -06 as I shoot it more. And so far, it's done pretty well; as long as I use the same motions/speed each time, I get very consistent charges. As to construction, the only gripe I have is that sometimes the o-ring doesn't put enough pressure on the tube and it can slip down; I'm thinking use a small round file to open the slot just a touch so more of the ring fits in. So far, when it's seemed loose I've just pushed on the ring over the slot with a fingernail. I'd think some kind of setscrew would be best, but they may have worried about someone getting heavy-handed and bending the tube.
Overall, I like it. It very much speeds up charging cases while still giving consistent weights. You'll note the clamp I've got holding it to the bracket for my Hornady measure, the 1/4" bolt, nut and big washers I usually use picked a fine time to go walkabout(the do sell a stand that's made for it). What I've had best results with is to make sure it's FIRMLY clamped to the stand, and when I lift do it quickly enough that I feel a sharp stop when it hits end of travel, then pull it down at the same speed; I find it easier(for me) to use that motion and speed consistently.
*worth it for match loads or hunting loads you want just perfect, but you still have the problem of most measures cutting granules; probably not enough to be a velocity/pressure problem, but not something I like.
