Every once in a great while, I find a great, or greater than the way I was doin it, way to accomplish a Handloading step.
I've got one I'd like to share, for your consideration, and also in the hopes of learning some method that you've learned or think is worth sharing.
I'm gonna start off with mine, and wait with abated breath for YOUR tip.
I trim my brass as a step in case preparation. I normally use my Forster case trimmer. If the brass is too long, enough, it will leave sharp edges, which I chamfer inside and outside. Nothing new here......
However, this process can leave a rough end, on the end of the necks, with shaving, even, but I've discovered a way to solve this problem, to the extent it is a problem. I don't like it, so I consider it a problem.
I got this partially from a source other than my own slow thinking brain, and so hopefully it's not as bad as some of my other ideas.
Get a Nut Driver attachment if you wanna use your Drill Motor, or just a Nut Driver if you don't. The Driver end should be quite a bit larger than the case neck.
Takey this Nut Driver and put some of that Brillo, Copper lookin stuff, or even Steel Wool into the Driver end, and press it down firmly. If you use steel wool, shouldn't matter if it's coarse steel wool.
With mine in my drill motor, I just push the case neck firmly into driver against the stuff, and give it a spin. It sure smoothes the end up, all rounded, like, I like it.
I hope that helps somebody, and I hope that somebody will pass along something of the same order.
