    Bought 50 pieces of new Peterson 308 SR brass. Thought I’d do an experiment of how perfect I can get the brass and if it even matters. Going to turn the necks, and uniform the primer pockets to start. My K&M primer pocket tool will not go into over 3/4 of the pieces. A couple that it would I had a hell of a time getting out without trashing the brass. Anyone have this issue? Seems very undersized.

    I have some Peterson small rifle 308. Never tried to uniform them they are tight, but from the beginning and after 3 reloads I have had no problems getting them to seat fully.

    Yes, it seems they do have some tight primer pockets!

    I started noticing this with my most recent batch of peterson. I ended up ordering a box of Alpha and have had zero issues.

    Peterson primer pockets are very very tight.

    Same thing happened to me on 300 Norma Mag cases. Ridiculously tight and couldbt seat primers all the way. Very difficult to cut and uniform. Good cutting oil helps the uniformer get in and back out a lot better. I called Peterson, told then about my issue, and sent in a few cases for them to inspect. They gave me a new box of 50 brass for my trouble. Good people that will make it right. Havent checked primer pockets on the new brass yet.

    I have 500 pcs. of Peterson with large rifle primers and they are very consistent in all dimensions and primer pockets are pretty good too.... just saying.

    Similar experience with Starline SR 6.5 Creedmore. Maybe 7 out of 100 cases.

    What if you just seated primers and loaded the brass?

    If the SRP Peterson brass is like Lapua Palma then the K&M standard SR primer pocket tool is slightly oversize. This was an issue for me when I bought my first lot of palma sr brass but was fixed when I bought the PMA tool:
