Cabela's has Federal Large Rifle Magnum Primers in. I do have a brick of CCI standard LR coming in, but have never worked with large rifle magnum in my 45-70. Dropping down to moderate loads. Additionally, changing up my boolit to 405 WFNGC from 425 WFNGC.
I understand we should start on the lower end when working up using large rifle magnums. Any issues with using these in moderate 45-70 loads?
