What are you using to uniform primmer pockets?

    I bought a bunch of Starline brass to form 218bee only to find, after going through all the necking steps, that about 1/3 of the primer pockets are too shallow to seat a primer correctly. I'm interested in what might work for cutting the pocket deep enough without spending a fortune. My lyman and RCBS uniforming tools are not cutting it. (no pun intended).

    I have the Sinclair tool...while it appears to be just like all the rest, it has a definite different feel when cutting. I don't know if it is sharper, but it works better for me. I have not used it in a drill or power driver because I don't have any brass that needs more than just a quick twist, but I would say it will do equally as well being used that way too.

    I use the Sinclair Primer Pocket cutter/cleaner that I have mounted in the Forster DBT Base and that combo has worked fine for many years and continues to do so. But I really like that new 21st Century primer pocket cutter/cealner device that appears to be adjustable. John just keeps coming up with new and more cleaver stuff all the time. Kudos to him and 21st Century.

    Don't understand why the RCBS uniformer won't work. Are you turning it by hand? I use an electric drill and use a little pressure.

    I use PMA's that was specifically designed for Lapua's slightly smaller pockets. I don't see it on Pat's website anymore, tho. It's adjustable, but not anywhere near as easily as 21st Century model. Still works well for me since I adjusted it once and haven't had to go back and do it again. At the setting I'm using, I get a nice shiny ring around the outer edge of the pocket on about 50-60 percent of my brass; about 20 percent I get a little bit of shiny on the entire pocket; on the remainder, I just get a cleaning of the pocket.

    K&M is very precise, adjustable but comes pre-set to the proper depth for the primer size you specify.

    If you can afford it, go with the 21st Century. It can uniform both large & small pockets with one tool...... If you plan on reloading for awhile and might be using brass made to Euro- standards the 21st Century will do any brass you might encounter without having to buy yet another "custom" adjusted tool. ........ Buy several reamers or buy one that does it all. ;)

    After dulling a few steel primer pocket cleaner/cutters over the years (45 or so) I got the Sinclair carbide cutters. I chuck them up in a battery powered drill with the adjustable speed control on the trigger. You may want to section one of the cases after reaming out the primer pocket to insure there is just to check how much meat is left in the case web.

    Sinclair tool chucked up in a hand drill. I use it as part of initial brass prep, then for every case cleaning thereafter. I find that it doesn't take any brass out on subsequent uses, but it does do a good job of cleaning the carbon out to the proper dimensions again.

    I do the same, with either a Sinclair or PMA but I do find a few cases, even after several firings, where a small amount of brass is removed which I attribute to the web being pushed back.

    Yes, I do see the same. I should have said "usually doesn't take more material out on subsequent uses". :)

    I have found that the brass moves around a little on the first firing, orientating its self to the chamber and taking a "set". I do the primer once with a Sinclair carbide cutter after the 1st firing, then never touch them again.

    K&M works great rock solid. I also like their case chamfer tool, it centers itself using the flash hole so it cuts an even chamfer on the case mouth.
