[QUOTE="eshell, post: 237720, member: 5747"] I'd suggest not using magnum primers unless proven necessary, and if you're shooting true long range, to check it for ES on your chronograph. I had used 215Ms in my 6.5-300 Wby with 83 grains of H-870 with decent results, but had to set the 30" barrel back and went with Retumbo in my "new" 27" tube. I continued using the 215M and then found I had wild ES numbers. In theory, this cartridge and powder should definitely require magnum primers, and I always assumed they were mandatory, but I went to a 210 and my ES went way down. I had to add back a grain or two of powder to regain velocity, but it's working well now. [/QUOTE]
