I decided to try W760 in my 7mm-08 Remington, and I have a bunch of brass already primed with CCI 200 primers. I know that W760 often requires a magnum primer, but does it require magnum primers in such a small case, filled to 90%+ case capacity? I'm using between 45 and 49 grains of W760.
Is it worth it to try these loads with the non-mag primers, or should I fire the primers and re-prime with magnum primers? What happens if you aren't using a hot enough primer? Hang fires, or just irregular velocities and poor groups?
