Hornady OTM (Open Tip Match) Brass & Priming Issue

[Devlin]

Evening all:

Looking for some insights as I was priming some brass I have been piling up from various range days. I had bought some Hornady OTM in .308 a few weeks back and burned through it all hanging on to the brass to use as reloads.

This is the stuff here

When I went to start priming the first of these rounds the primer would not go in and I didn't want to force it. I'm priming on my press and have never had this happen before, the press is a Lee turret press and yes I had the correct anvil in for seating the primer. It was going into the Federal brass I had with no issue at all. I'm new to the world of rifle reloading and take things very slow and the minute I have an issue I back away from it until I understand what's going on.

Is anyone familiar with this brass? Upon closer inspection the primer pocket on all of the Hornady rounds has what I would call a thin wall or steel band within the primer pocket, almost like a ring of brass around the edge of the primer pocket wall.

Is there perhaps a special primer for this type of brass?

I was priming with Federal Large Rifle "Match" primers.

Thanks for any insights you may have.

Some Hornady brass has crimped primers, you can remove it with a case mouth deburring tool.

Crimped brass. Federal is also crimping now. A few turns of the deburring tool will get rid of it. I have done that to a few hundred or so cases.

Crimped primer pockets are a pain. I put a counter sink tool (about $6.00 at Home Hardware) in my electric drill when I have to de-crimp a lot of cases.
