I notice that Lyman doesn't specify which primers were used for the loads that it lists. For example, for .300 WSM loads where it lists the barrel, twist rate, action, bullets, primers etc, it simply states "primers: magnum and standard large rifle" or words to that effect. I'm working up hunting loads for my .300 WSM using a Hornady InterLock 150gr bullet and IMR 4895 and have both magnum and standard large rifle primers and was wondering which would work best. With no guidance from Lyman I figured I'd ask here.
I've been shooting 168gr bullets using Reloder 22 with magnum primers. I use standard primers and Reloder 15 (or 4895) for my .308 but I'll be using about 50% more powder in the .300 WSM. Reloder 22 is a slow powder compared to IMR 4895 so my intuition tells me that a faster powder would work fine with standard primers even though there's 50% more of it in this case (no pun intended). Any thoughts?
In general, how do you decide whether to use a standard or magnum rifle primer?
Thanks.
