New to 10mm and reloading

[sqlbullet]

What method you choose for removing the crimp depends on a bunch of factors.  The cheap options are not usually fast.

Methods I have used:

Ream (Deburring tool) - I used a basic case chamfer/deburring tool.  Couple of twists of the pointy side in the primer pocket usually does the trick. 

    Pro:  cheap and effective, especially since most of us already have the tool. 
    Con:  Removes metal*, slow, not suitable for a large amount of brass.

Ream (Reaming tool) - A couple of years back I found a purpose build primer pocket crimp reamer from one of the big boys (RCBS, Lyman, Hornady).  The tool is designed to be attached to a case prep center and has a threaded shaft on the bottom.  I just chucked it in a drill.  The advantage of this over a deburring tool is this has a ledge that stops the reaming once the pocket opening is correctly sized. 

    Pro: Effective, fast, easily powered, and automatically stops once the correct material is removed
    Con: I can't find it again for sale

RCBS Primer Pocket Swage - This is a press mounted die set.  It has a couple of components.  The swage itself locks into the ram and has a button on it that will swage the pocket.  There is a collar that goes around the ram and button so at the bottom of the press stroke the case if forced back off the swage.  And there is a die that does in the press that supports the case head from the inside so you aren't stressing and/or collapsing the case body.

    Pro: 
    Con:  more expensive and slower than the reamers.  The swage has to be well lubed, and you still bang on the ram often to eject a case

Dillon Super 1050 Reloading press - So, a couple of years ago I got the idea that I was going to retire from my day job and make money processing once fired military brass.  I won an action for over a thousand lbs of 7.62X51/308 brass.  Since I knew many of my potential customers might not like reaming, which is what I personally did, I bought the RCBS swage.  about 1-2K rounds in I threw in the towel of processing the brass single stage and ordered a Dillon Super 1050 set up for 308.  The machine has an on-press primer pocket swage and was a revelation.  It is smooth and fast, and completely integrated with progressive action for de-cap, size, swage, and trim.  The first couple thousand rounds took me a week of after work nights.  First night running the Dillon I processed 4K round and all I had to show for it was a sore but from sitting on the stool.

   Pro:  Work, does it inline and pre-prime step, would allow in 10mm mixed crimped and uncrimped primer pockets, progressive with other steps
   Cons:  $$$$, and only a 1 year warranty on the Super 1050.

If I were to call out a preferred solution short of the 1050, I would just use my deburring tool in a drill and be very ginger.  It doesn't take much, just a kiss.


*Removing metal from the primer pocket is considered a capital offense by some reloaders. Gospel of sqlbullet is don't over-do it and you are fine.  After all, the actual primer pocket crimp doesn't contribute structurally to the head pre or post swage.  But, if you chuck that deburring tool up to a drill and really go nuts, you can badly compromise the primer pocket walls and greatly increase the risk of a blown primer.

Have u reloaded the Magtech brass?

I found a few dozen rang pickups. I happen to think that Magtech brass in general is pretty decent. One peculiarity with the CBC (Magtech)  headstamps is that the primer pockets are staked. So I swaged tbose primer pockets before loading.

Evil satanic bastards that created crimped primer pockets. The scourge of progressive reloading!

 It is curious to me how much commercial ammo has crimped primers. That is particularly true of 223.

Years ago I bought the RCBS press mounted die set thinking I'd upgrade to a Dillon Super Swage if volume increased. Well, volume did increase, but I ended up liking the tool more than expected. Several thousands of swaged rounds later, I haven't felt the need to upgrade.

I invested in a Dillon Super Swage and I must say its wonderful. You can set it up with a rubber band ejector (YouTube ) and you can go quite quickly. I also have the RCBS motorized case prep station that I used to cut the crimp off with; needless to say it only gets used for neck chamfering since I got the super swage. For 5.56 I set it up for LC brass and it works great for all other stuff I've encountered (Hornady, Fed, etc). Definitely worth the investment if you're going to be loading alot in the future.

One that Shadow listed - Underwood's Range Supply 10mm / 180 Grain Full Metal Jacket isn't the cheapest, but is great stuff

If Georgia Arms still loaded with Starline Brass, I'd probably do that.

I mark all my 10mm brass for ease of pickup. Hate to loose any of my starline.
