I' ve never seen the need for magnum primers in the 25.06. I use CCI 200 primers in my 25.06 with a 120grn Speer Spitzer and imr 4831. The imr 4350 shoots good with some bullets in my rifle but the 4831 shoots the heavier bullets much better.

I used to use magnum primers when the load data called for it, but I don' t use them anymore with extruded powders. I seem to get better results with Win large rifle primers than I did with the CCI large magnum primers.

I HAVE ALL WAYS USED CCI PRIMERS
