It’s a little blurry, but I’m sure you guys can at least see the chart on the third page.
It has a nice article on the 360 buck hammer with load data to.
FYI…this Hodgdon’s load data magazine was at my local Walgreens!
I don't think there is much difference in 'Brisance' - or what ignites the powder. In my experience the main difference is the stiffness of the priming cup. It may be thicker or it may be made of a tougher alloy for magnum use. The magnum primers have tougher cups. I learned this while loading for my Marlin 1894C in .357 Magnum. Because the rifle is a rifle it occurred to me that I should use Rifle Primers. They allowed me to increase load data without excessive pressure over pistol primers. No problem. But when I tried using small rifle magnum primers I encountered misfires. I took that to mean two things:
1. The rifle's hammer fall was designed for pistol primers.
2. The difference between Small Rifle primers and Small Rifle Magnum primers is the toughness of the primer cup.
Hope this helps.

I remember reading an old article with photos showing the “Braziliance” (sparks) of each primer tested and how far out they shot sparks. It was pretty interesting, but I don’t remember the article.
This one was similar

I dont see changing from standard to mag, being a large issue. But, drop back on the powder charge some, and work up.

The differents between powder lots is more important, imo.
I found some LRM primers (26) in a box bought at auction. With the lack of LRP, I began searching to see if I could use them in my 308 instead of passing them on. So now I know that if I need to, I can use them. I love this forum. Thanks everybody!
