Going to dabble some in the ELR world and have decided to spin up a 300PRC and a 300NM. We don't have many opportunities where I live so these calibers will meet my needs.

My question is what's the consensus or is there one on primers? I see where some are using LR primers and some are using magnums?

My goal here is like everyone else in making a load with the lowest SDs and ES possible, appreciate the responses.
