I acquired some Win Large Rifle Magnum primers (WLRM). Most of the data I can find warns that the magnum primer should not be used in place of a Large Rifle primer due the chance of much higher pressures. However all of the warnings are accompanied by the statement that you can work up a usable load.
Question--Where to start? 10% below the starting load or more? The powder will be IMR 4064 pushing a 165gr Hornady SST in .30-06.
