Had a little time and decided to load and test the 12 pieces of Norma 6ppc brass that I have reloaded 8 cycles. The primer pockets on 6 pieces are not as tight. I backed down to 29.2gr N133. Wind 5-15mph.
I shot t foulers and the shot the 12 Norma rounds at the same target non stop. The first five shots low 1s. The first 4 in the same hole. Forcing that fifth shot a bit. The next seven opened the 12 shot group up to about .26 but there were no fliers. 29es 3317 avg fps.

Had heavy bolt lift with two of the shots. Primer pockets toast. 4 of the others not far behind. The Norma brass was new. I had used Lapua brass fired unknown times that I used for foulers and the pockets are still tight.
I will use the rest of the Norma but will not buy any more. It is as accurate as the Lapua but the primer pockets are not as stout.
