So tomorrow I'm going to Cabela's in Delaware to pick up some powder. I am running low on primers for my 30-06 & 243. Everytime I've been to Cabela's they seem to have everything but large rifle primers. Can I get away with using magnums. I know I would have to rework my load's. I wanted to order an 8 pounder from mid South,but they were out of large primers also. I live about 20 minutes from bass pro in Maryland, but they charge between 6-7 per 100 on primers and they're powders are always about 10 dollars more than Cabela's. Plus they don't charge tax up in DE. Thanks in advance for your input.
