Large rifle vs. Magnum primers

[CRNA]

Don't have a manual yet, but when loading a 7mm Rem mag does it require large rifle or magnum primers? Thanks.

Typically LRM, but I have heard of good results with regular LR.

I would start with the LRM and see what I could get out of it. Then I might try LR if I were not happy with the results or got bored.

Changing primers, powder type, and powder weight will change POI.

No personal experience with th 7mm RM.

Get a book or three and start reading before you start stockpiling components.
