I've run into the same issue with this particular brass as I have with Blazer 9mm brass.

Not enough neck tension after sizing to properly secure the projectile.

The other headstamps mixed in to include R-P, Winchester and FC were all fine.

I just ordered a 44 mag undersized die.

I ordered a couple hundred primed Ammo Inc brass from American Reloading a while ago. The first load was fine.

It must be thin brass.

Just a heads up.

I don’t know much about AMMO Inc brass, but I haven’t had any issues with Blazer 9mm brass.

I might suggest looking at a smaller expander for your .44 Mag loading.  In particular, if you’re loading jacketed bullets, make sure your expander isn’t large enough to expand for lead bullets.  The difference between expanding enough for a 0.429” jacketed bullet and a 0.430” lead bullet could be enough to wreck your case mouth tension.

Agreed. I have a bunch from a Cabelas sale a few years back.

I'm sizing a 100 new pieces now.

I've reloaded some ammo inc 300 win mag brass a couple times and it seems ok. I bought it ass pulldown primed brass.
I have some more ammo inc headstamp primed brass, but I can not remember if it was 9mm or 45.
I'll have to dig around and see.

I have heard that the ammo inc rifle brass is allegedly jagemann. Now weather that is true, I do not know.

I’ve shot a lot of the 44 magnum Ammo Inc primed brass.  Got it from CDVS probably a year ago.  Dillon 550 and a mix of Dillon and RCBS dies.  All coated lead so far.  Zero issues with moderate to medium loads in revolvers and lever guns.  I’m using a Dillon expander/funnel.  Everything else is RCBS.

I have a lot of the ammo inc brass in multiple cal. I have not found any that gave me any problems. Only ones I am having issues with are Extreme and MXT. Both give me very hard seating and primer pocket issues. I am slowly going through my hoard and getting rid of anything with those stamps

Lee undersized FL die worked like a charm.

This was 100% a brass issue.

Again, these came from AR, and feedback above suggests ammo inc is good grass, so it seems to be an isolated issue.
