First, what's the difference between the Winchester primers in the red box vs the blue box? I had some failure to fire issues with Winchester SPP in the red box and ended up sending over 1400 of them back to Winchester.
Second, how does Winchester make these LPP suitable for both standard and magnum loads? I've been having problems finding Magnum LPP so I ordered some of these. I'm guessing it just a magnum primer and it doesn't hurt to use them where magnum primers aren't really required? I experimented with magnum SRP in my 6.5 CM and I got better ES and SD numbers, but didn't see any measurable increase in accuracy so I went back to regular SRPs. Is this a similar situation?
