[QUOTE="Browninglover1, post: 513410, member: 29966"] Jimbires is right that there is enough of a difference between small rifle and large rifle primers in terms of diameter that it is impossible to screw it up. However, there are Large Rifle Magnum primers and standard Large Rifle primers. For the 300 win mag you're shooting you should be using Large Rifle Magnum primers according to all my load books and just a standard Large Rifle primer for the 308. The difference between the Magnum and the Standard primer is how hot they burn. The Magnum primer has a hotter/bigger blast to help light bigger amounts of powder (especially in the cold). If all you have are Large Rifle Magnum primers they should work just fine in the 308. I've loaded them in a 308 and 270 before, because it's what I had on hand, and both worked fine but I did need to reduce my powder charges to get rid of excess pressure signs. Just reduce your starting loads by a few grains and work up watching for pressure signs. [/QUOTE]
