"Dam this primer is tough to seat !!"

Road_Clam · December 23, 2016, 09:34 AM

So i'm loading my AR-15 "winter plinking" ammo which I take all my "no name" misc brass , load a mild charge of 25 gr of W748 and load 'em up. I use all my range scrounged misc brass so that when the fired casings get launched into the deep snow in front of the firing line I don't care about the brass and don't have to go digging through the snow to retrieve my casings. Loading with my LEE CT, this one casing was being very stubborn for a primer seat, i chamfered out the crimp and tried a few times to seat the primer, it wasn't fully seating, I tried a few times rotating the casing and putting some muscle on the turret lever and something just wasn't working as it should. After an inspection:

Yup, this was a first for me ! LOL

Minorcan · December 23, 2016, 10:08 AM

LOL .... If this was the first time this has happened to you don't worry it wont be the last .... don't ask how I know this

g.willikers · December 23, 2016, 10:15 AM

Heck, it'll fire that way, you just need a firing pin with a little hook on the end.

Finding brass in the snow isn't hard, you just have to follow the little holes they make.
Like hunting moles.

Korean military brass.
Looks like crimped primer.
You need to ream that primer crimp to prevent this.

ed308 · December 23, 2016, 11:53 AM

I think that PMC's military brass. Heavy crimp but probably good brass. Don't see much of that around my area.

Longshot4 · December 23, 2016, 12:44 PM

Looks like you need to wake up your sense of touch. Feel with your finger tips and you will learn to recognize the feel of interference.

It's kind of like jigging for walleye. It's a feeling thing. Pay attention and slow down.

kerreckt · December 23, 2016, 12:45 PM

Looks like crimped brass, to me. You must swage or otherwise relieve the edge of the crimp so the primer will fit.

Chainsaw. · December 23, 2016, 12:58 PM

Yup. Has that happen a couple times. I just chuck the brass at that point.

SARuger · December 23, 2016, 01:27 PM

I loaded 500 rounds of blasting ammo last weekend and had three do that. Got two of them to finally work, one went into the scrap bucket

mikld · December 23, 2016, 01:29 PM

Wow, that never happened to me, nope never (that's my story and I'm stickin' to it

). I think there is still a bit too much crimp in that case and that's why I use a tool to cut out the crimp...

Sure Shot Mc Gee · December 23, 2016, 01:34 PM

I've done a few myself. Sideways up-side-down and none at all. (None at all.) Boy are they fun to deal with when the powder charge is Ball Powder.

Will it shoot around corners?

I've "seated" a few primers like the OP did, but had a first for me last week. Was inspecting some 45 ACP that I had just loaded and found one with the primer nicely and completely seated... upside down. Just disassembled the cartridge and rebuilt it the right way.

nhyrum · December 23, 2016, 04:40 PM

Do you use Lee's safety primer feed? I've had small primers rotate in the feed way.

Road_Clam · December 23, 2016, 05:07 PM

I actually did attempt a chamfer to remove the crimp after the first time inserting the primer was a no go. What i've realized after doing about 30 of the same brass is that the primer crimp is VERY tough and takes a fair amount of pressure on my chamfer tool to remove the crimp. I also noticed that Tulammo brass 223 has a very tight fitting primer pocket as well.

EchoBravo · December 23, 2016, 07:38 PM

If you don't have a ton of cases to de-crimp, this tool is cheap and does a nice job:

Unscrew it from the handle and chuck it in a cordless drill to make it easy. Good to have on hand for whenever you get some brass with crimped primers.

I have the Lyman case prep Xpress center. Very happy with it and it makes short work of all the typical case prep operations.

Apparently, it did not for your pictured PSD 13 case.
I use an $8 countersink bit in a $20 cordless drill.
If the Lyman case prep Xpress center does not handle that crimp, then I do not need one.

I never said anyone "needs" the Lyman case prep Xpress. Use your $8 countersink bit in a $20 cordless drill and i'll continue to use my Lyman Xpress. Go back an read post #14 again. I did an initial chamfer on the but did not inspect the casing for a true adequate chamfer after the task. I tried a couple times to seat the primer and obviously the primer lifted out of the cup and flipped 90 degrees and I unknowingly jammed it in the casing. Simple mistake on my part, no need to be condescending.

Metal god · December 25, 2016, 12:38 PM

I just don't see how anyone could ever seat "a" primer in that way

Because when it happens to me it comes in waves lol

Merry X-mas

Marco Califo · December 25, 2016, 01:45 PM

I did not mean to sound condescending. I actually priced the Lyman yesterday, and, compared it to the Franklin Arsenal case prep appliance. The latter also trims cases to a uniform length. I understand the Franklin accepts RCBS tool heads for the primer crimp removal. Trimming length is a game changer for me, as I use milsurp 7.62.
The great thing about the drill and bit is exactly one second on the trigger leaves a uniform bevel, and no crimp. The cut is very shiny, making inspection easier and quicker.
I have had a few sideway primers and notice this most with my RCBS hand primer. If it doesn't feel right I stop and disassemble if necessary. I bought their new Universal hand primer, but have not tried it yet.

Longshot4 · December 25, 2016, 03:36 PM

I have had the same problem although I believe the tool was at fault.
But don't quote me on that since it hasn't been recently.

Panfisher · December 25, 2016, 03:37 PM

I like to prime on the press, so it's pretty easy to do with that much leverage on the ole rock chucker. I just punch them out and seat a new one.

Zorro · December 27, 2016, 04:13 AM

Bad Case, toss it.

FrankenMauser · December 27, 2016, 05:03 AM

Thought I replied a few days ago.
The internet must have eaten my homework.

Short version:
I did that a few years ago with a Lee shell holder in an RCBS priming tool, at 3 am, and scared the crap out of the whole household.
BANG!
They thought I had shot myself.

(Lee shell holders suck. They're bad in their own tools, and even worse in other brands of priming tools.)

Marco Califo · December 27, 2016, 05:20 AM

Lee makes 26 sizes of shellholders (some fit multiple cartridges, sometimes losely) while RCBS makes 54 that all fit properly.
When I noticed the wobbly freeplay, I stopped buying Lee shellholders.
