Flattened primers do not mean much, but when the primers fall out after four loadings, it does mean the load is too hot for the brass.

I often load one piece of brass multiple times to test for primer pockets becoming loose.

Primer choice? I have never found any thing better than CCI 250s in 30-06 or larger capacity using 4350 or slower powders. I would start with H4831 in your WSM, and perhaps experiment with Accurate Magpro or Ramshot Magnum as they are very dense and you can get high charge weights without compression.

The slowest powders in the IMR Enduron line look promising, but I have no experience with them at this time.


Yes sir, tired some of the more promising loads over again with the 1x fired brass, no flat primers or powder crunching. As I mentioned in an earlier post, the primer pockets were VERY tight on these to begin with. I assume that had to do with the flattening. The 1x fired brass was also easier to seat the primers this time.

I had palnned to try 4831 but due to the initial case capacity on the Norma brass being less than most brass,I wouldn't be able to get enough powder in to get to the velocity I was after without running compressed loads. Im pretty much sold on the Extreme pwders from Hodgdon. Ive had excellent results in all temps with it thus far.
