Home Forums Reloading Varmint Rifles Crimped primers

I'm going to have to start wearing those, I guess. I have blisters on 2 fingers and a thumb from doing case prep by hand. I didn't have that problem before I retired. Guess I'm getting soft!

Bought one of these off Hanco for $50 or so... best $50 I've spent for my reload bench...

I had the Dillon, faster and easier with deburring tool.

I couldn’t remember who I sold it too, glad you are using it.

I use the Wilson. I take knob off, buy adapter, chuck in battery powered drill.

Hanco, I couldn't tell from your picture, but does that thing put a round shoulder on the primer pocket?

Just a bit, cuts crimp right out. I leave drill on table, hold brass in left, hit drill trigger with my right hand about a second, done deal.

Here is mine, can only go so deep.

Okay, I think I've seen a cutter like yours. I just use a countersink in a drill press, put a chunk of rubber on the plate and zip zip zip, whacking out a nice bevel. Your toy might work better.

Anyone know if three equiangular dots on the FC 223 Rem brass indicates crimped?

Yes it does.

Yes the multi dotted FC .223 are crimped. All of the Federal .223 that I have seen, dots or not, since at least 2007 are crimped. Most of the Winchester except some of the hunting loads are crimped. I have not seen any Remington or Hornady that was crimped.

Thanks Swifty and mag.
The in unsealed ones don't appear crimped and have the headstamp in larger text.
The sealer makes it hard to see the primer edges of those particularly since the natural light is not so good today and putting under a lamp gets too many reflections..

I have read the some of the older, bold lettered, FC .223 brass is very thin through the head and is not worth loading. I started hand-loading in the mid 80's but came to .223 reloading late enough to miss the bad brass. The few bold letter FC .223 brass I have stumbled upon just went into the scrap bucket.

Hmm.
Wonder if it is pre LC contract...

You mean the web is thin?
Or the walls just ahead of the web?

I suspect the crimped primers and ATK taking over the Lake City plant in 2000 happened about the same time.

The web is thin. One or two loads and the primer pocket expands. I check several that I scrapped and some were ok and some were noticeably thinner. I set up my RCBS press mounted primer pocket swage, which uses a punch though the case mouth to push the shell case down onto the "nipple" that swages the crimp into the head. Set up for a normal case some of the big FC cases were a loose fit. If I had a large number of the big FC cases that is how I would segregate the "thin" from the normal.

Most of the Hornady that I have been picking up are crimped.

Well damn. In the end it is all probably going to end up crimped.

Prolly so!

Thanks I was thinking of how to measure the web..
As measuring depth from neck would be meaningless.
A drill press might work. But the stop adjustment isn't nearly as fine as a sizing press.

How long they last depends on how hot you load them too. Less pressure less stretch.
Good for sub Sonics at least.
