I purchased a 5000 primer case of remington magnum primers about 30 years ago,Ive had several problems over the years with Remington primers failing to fire or hang fires in extremely cold weather,in my 375 H&H and 378 wby so I gave those away to friends that wanted them AFTER explaining WHY I would not use them.,
both caliber rifles use fairly large charges of hard to ignite powder,this has made me a firm believer in the FEDERAL 215 primers, which has never been an issue with federal or Winchester so I just don,t use Remington any longer, I think part of the problem might be related to thicker and stiffer primer cup metal in the Remington because the indents don,t look as deep in the fired cases as they do with the fed,Winchester or CCI primers.
it was easy to tell because the GOLD color Remington vs the silver federal primers, I usually load up 120 cartridges for a hunting trip, just in case, but seldom use more than a couple to verify zero and one or two to kill game. one year I loaded about 200 because both my sons carry 340 wbys, and I loaded 40 with remingtons. both my older son and I had hang fires, both with the gold primers.
ID suggest sticking to federal and Winchester primers if you can get them
CCI seem to work, but I have used those only rarely, I usually buy primers in 5000 bricks
Ive never had an issue in smaller case cartridges like 30/06 with medium burn rate powders but having the issue in the larger cases makes me avoid their use.
I would also point out that some calibers like the 45/70 do with reduced pressure loads tend to have a bit better accuracy with the standard vs the magnum primers so keep that in mind
