Rapidrob Wrote:Magnum primers are hotter. Greater initial pressure is generated as the primer fires. The initial rule of thumb is to reduce your powder load by one full grain. For those of you who are using a max loading now, you can get into trouble just by changing to a magnum primer. Please be careful I'd hate to see anyone get hurt or ruin a good rifle.

Not to mention a good face.
One should also be careful using WSR primers. There is a higher incidence of slam fires with the new WSR primers. Apparently the new copper tinted primers are a lot softer than the older chrome colored ones.
