Trouble with Remington primers

[Russ16]

I’ve been having trouble getting my Remington Magnum Primers to seat in both 375 H&H and 30-06 brass. I’ve used a primer pocket uniforming tool. It doesn’t matter if I use my Lyman hand primer or the tool on my RCBS press about two thirds of them won’t go fully flush. They sit up just a touch. Barely perceptible to feeling with your finger but definitely a wobble when placed on a flat surface.

I’m starting to think the primers are just a touch too tall.

Has anyone else run into this? Did you do anything to correct it?

Thoughts welcome.

They could be a little out of spec. Try a different box or a different brand and see how it works. Lean on the RCBS handle a little harder.

I think the Rem 9 ½ may be slightly larger in diameter than other primers. I have noticed that they seat harder than Fed or CCI. Try them if your primer pockets get a little loose with other primers.
I am now using a Primal Rights priming tool and it seats them with ease. A buddy of mine threw away some Rem primers because he couldn't get them to seat, so I think they are just a bit larger in diameter than the others

@Russ16 I also had problems fully seating the Remington 9 1/2 Magnum primers but for me, only when loading new Nosler 500/416 brass. I was saving all my Federal 215M primers for hunting and figured out how to uniform the primer pockets in the new brass.

I measured Remington compared to Federal primers and found the formed to be slightly larger. The Remington are great for loading brass when the primer pockets have expanded a very small hair...

K&M also offers adjustable primer pocket uniformers (cutters).

Frankfort Arsenal offers a priming tool with adjustable depth.
K&M's priming tool is also adjustable and has a gage to seating measure depth. This one is great for inspecting primed cases!

Thanks.
