seasoning new brass?

yes normally i would agree with you both BUT. i have a batch of 6.5x47 brass that i did barrel run in with and have loaded around 5 times with warm loads and they are still accurate and the primer pockets are still nice and firm.
i had another post earlyer about loose primers on new brass and thought it was because i had loaded several months in advance that caused the bullets to adhere to the case necks over time. thus causeing excess pressure.
this time i loaded just enough new brass for the weekend. after coming home found that all the cases now have loose primers and are now ready for the bin!!
so my question probably should have been why the hell are the older cases standing up to 5-7 loads and i cant even get 2 out of the new brass!
the neck wall thickness, case weight etc etc is near identical on both batches but one lot is about as tough as a marshmellow in a pillow factory!!!!

I am in the process of "hardening" some 284 Shehane brass. The 284 case is a rebated design which I have been told gives the head less support and results in the loose primer pockets I have experienced. "Hardening" was suggested by a shooter of great experience whose opinions I respect, and so far I believe it is working. However, I do anneal my cases before every match so the concerns expressed by others here have not been a problem for me. Also, the 6.5X47 case is not a rebated design so the loose primer pockets you are experiencing may not be caused by the same issues as mine are.
