7wsm, Fed & Win brass, Fed 210 primer. H4831SC. Loads starting at 52.5gr to 58.7 gr. Sierra 175 gr GK. Shot from Win. 1885 Highwall. Not really hot, but primer mark on all of them is pushed back out and flat. This is happening regularly with this rifle. From hot factory to soft hand loads. At this time I am not really concerned as there are no other signs of high pressure. I sure would like to know if I am missing something here.
