Tight primer pockets on Nosler brass?

[Alderman]

Was loading up some new 308 Nosler brass with Fed 210M primers.
The primers were harder than usual to get seated fully in the primer pockets.

Almost as if a two stage process
where they would go 1/2 way in then take quite a bit of force to get them flush.
I don’t know if it’s smaller primer pockets or larger primer diameter.

Anybody else have any experience with this?

I had the same problem with Fed 210M in new 22-250 Lapua brass. It was so difficult to seat them that they were getting flatten out, some wouldn't go in at all. I thought it was the brass until I tried some CCI LR primers and they went in fine.

It pains me to say this, but I quit using Nosler brass some years ago because so many of the cases had tight primer pockets. The first I noticed was on the 260 Rem brass. There were other cases after that, so I just quit buying Nosler brass. I still have boxes of Nosler brass that I'll never use because of that problem.

I had some 6.5CM once fired that I could not seat a 210M into, no mater how hard I pushed.

Get yourself one of these. It can be used with a cordless screwdriver, I use it by hand. Makes every primer seat the same, regardless of what case it's being put in. Some cases it takes very little out of, some quite a bit. It's meant to set the depth, but also uniforms a primer pocket if one is out around or tapered.

If I have 1 that is really bad, I hit it with this first just so the correction tool can get started, and turn in the pocket. Rarely have had to use this first, but I had some Winchester brass in 22-250 that needed it.

Used several tools, but the ID of the pockets was extremely undersized, necessitating considerable work to ream them out to accept a Federal or CCI primer (steel cup).

Well at least I know it’s not just me. Thanks for the replies.

I've had a few problems with Nosler brass , extremely tight primer pockets was one of them . I used the tools for pocket uniforming , it helped but did not fix the problem .

I had that problem with Sellier & Bellot brass.
Their own primers fit well, Federal not at all.
Stopped using that brand of brass.
You might try S&B primers, if they are available.

Jim, curious if you have the K&M tool? I've no way to determine as I don't have the Nosler cases to work on, so they might indeed be unfixable.

Just hard to imagine they could be worse off than the bag of Winchester 22-250 brass I went through. They are what made me buy the K&M, as initial use revealed most cases being extremely hard to seat, and others unable to seat.

I have a similar tool made by Sinclair before Fred sold to Brownells. Made of solid carbide with an adjustable collar to set depth. Takes care of the problem as you suggested.

I think my cutting tool is from RCBS . I've had it for many years , probably before there was a K&M . my tool seems to cut depth , with a flat bottom . didn't seem to cut diameter much at all .

I remember fighting with the nosler pockets . I'd think I had it solved , but it wasn't . I made a thread about the brass on the forum , showing how consistent it was in capacity . that batch of brass was exceptional , but the primer pocket problem was a headache . then I ran into other issues , so I don't use it any longer .

when seating a primer , the primer should be bottomed in the pocket . it should be slightly below the brass case . it should have .002" crush per CCI recommendations . with the pockets being that tight , the primers were probably damaged to the point of being inconsistent . I had flat primers from installing them . LOL

Nosler brass is all I run in my 7mm Rem Mag (got a bunch when I bought rifle) , after a couple of stiff loads they’re not tight now.

We shot some this afternoon and no issues. Things looked good after firing. The guy pulling the trigger is a better shot than me so the hand loads worked well.

my pocket cutter tool looks about the same as the K&M . the only markings on mine is "LG" I'm assuming large .
