... I have a favor to ask. First, I am an idiot. I had a chance to buy one of these last week at a gun show for $15 and have been kicking myself ever since for walking away without it. But I'm a DIY kind of guy and figured I could make a tool that would work adequately, since I really only care about swaging .223 and not very much of that. So today I chucked up some sufficiently hard steel in the lathe and made a tool that almost works. I figure I must have missed something obvious, and since nobody near me has one I can examine, I throw myself on your mercy. I measured the primer pocket in a piece of PMC brass and a small rifle primer, then made a punch that duplicates the primer pocket dimensions: .174" diameter by .121" depth. Like I said, it almost works. So if somebody could, please measure the little nubby punch on the RCBS small rifle tool and riddle me this:
1. What are the actual dimensions of their punch?
2. Is it straight walled like a primer seating punch, tapered, or otherwise shaped differently? (I've slept since I looked at one and can't remember what it actually looked like) (24 megapixel macro pics might help also )
3. Any other obvious thing I'm missing? Besides brain cells?
And if you're scratching your head (shoot, I'm surprised I've kept your attention this long), I built a punch to replace the primer seating stem on the Rock Chucker priming arm. The body of it is full diameter fit of the ram slot, so the casehead bottoms out on the punch, rather than the swaging part pushing on the web of the case.
Thanks in advance. You may now return to your regularly scheduled programming.
