AMNT headstamp

Headstamp of 

AMNT 223 REM. 
 

Anyone try to decap this headstamp?   Sukx.  Won’t decap. 

I’m decapping on a rock crusher and only this headstamp pushes out my decapping pin. Anybody else run into this headstamp and why won’t it deprime. Sux sux sux.

That sucked.  That headstamp just broke off my recapping pin. FFFF

Are they Boxer primed?

What is boxer primed?

I suppose it cool because I got about 1K deprimed.  Before it broke.

Has really small flash holes you have to use the very small diameter ones. The ones you decapped you may have reswaged. Using an .060-.062 and maybe a tiny bit of case lube on the pin itself should help but you likely want spares. 

I run the tiny decap pins for all 223 as Lapua is a bit close also.

A mutant ninja turtle?

 

If its an issue is there sealant on primers?

These and others with something like IK-22 or JK-22 have really nailed me on de-capping pins lately. I had to hand sort a 5-gallon bucket of cases to get them all out after breaking/bending multiple pins. 

The flash hole is SUPER small.
