[QUOTE="Pdvdh, post: 1221119, member: 4191"] Shortly after [B]tbrice23[/B] created this Thread, I internet researched this subject and found and e-mailed a man in Canada that made something like this tool, on a custom order basis. He didn't stock them. He was making them one at a time out of his machine shop, and the cost was in line with one-at-a-time manufacture, compared to mass production. It looked like a nice tool to swage down primer pockets (PP), but I decided it was simply too expensive, relative to the cost of purchasing new brass and discarding the old. Before you spend the additional money, you might try the tbrice23 method. It's not overlying expensive, complicated, or difficult, once you get the right size bolt shaft and ball bearing. And an extra blow or two with the hammer won't damage the case heads if you have a carbide PP uniformer (I used a K&M tool) and use it in a battery powered drill to remove the excess brass in the leading edge of the primer pockets. It takes several, typically 3-4, hammer blows on the bolt shaft, to tighten up the PPs. So it's not like one individual hammer blow it going to ruin anything. Just keep your dial calipers handy and measure as the primer pocket is reduced in diameter from 0.210"+ down to approximately 0.208". [B]tbrice23[/B]'s method, and the associated cost of the required items, is more in line with what I was willing to spend to salvage some over-pressured casings. You can buy 10 ball bearings for maybe $6, so even if half of them fly through a window and rocket off into the woods, you're still in business.
