Hey guys, I am gonna be loading 440 hard cast gc bullets for the 500 s&w. My question is which type of primer to use. My cases are marked with R which means rifle primer. But Ive heard the H110 needs magnum primers. Any suggestions??
I did load them with 16.6 grains of Titegroup shot great with the LR primers CCI.,
