    Reaming Military Brass Primer Pockets


    What do anyone of you think is the best and fastest way to ream military primer pockets.Mostly 223 brass.I have a lot of it and am thinking about loading this caliber.I did load one box already with a set of dies I got in a lot of equipment I bought .I know from experience that reaming primer pockets can be a chore.I have heard the Dillon is ok but was wondering if there is a better and faster method?I might be better off just getting good new brass for my AR.I would like a few thoughts.

    I use a rotory rasp in a drill. It is quick and easy.

    I use a Hornady primer pocket reamer chucked up in a drill.

    Just keep the drill speed fairly slow, and process away.

    I also purchased an RCBS swager and was less than impressed.

    I have tried them all and prefer my Dillon swager. RCBS swager is second. Rotary styles work but I prefer swaging.

    The Dillon is a good unit, I have used it for several hundred different cases. I tried the RCBS and did not like it. Anymore ,I use a drill that I ground to the shape and size I wanted. 1 large and 1 small. I had 2 5 gal buckets of 30-06 match from Fo 57 and it was crimped. and a lot of military FC 96/97/98 45 auto that is crimped. My drills are faster and easier.

    I use myRCBS chamfer tool. Quick twist and the pocket is good to load.

    $3 carbide countersink bit from the hardware store, chucked in a drill.
    Takes anywhere from 1 to 3 seconds per case.
    Now I do them by the thousands with ease.
    Sorry I spent so much money on swager and reamer tools over the last 30 years.

    The advantage of reaming is when you pick up a couple thousand cases after a match.
    The reamed cases are identified in an instant, and you know the pockets don't have to be processed.
    If you swage them, you can't tell by looking.

    Thanks for the replies.How do you hold the case when you use a drill to ream the pockets?

    Fingers, it doesn't take too much pressure to do the job.

    Yep, fingers. You hardly have to push the drill. A carbide bit cuts brass very easily, let the tool do the work. As with any power tool, don't force it or you might slip and ream a primer pocket in your thumb.
