I am just perusing some reloading data for my 300AAC as I am about to do a few trials with different projectiles, and in doing so, noted that there is a discrepancy between different manufacturers data with the use of small rifle primers, and small rifle magnum primers.
For example, ADI, and Hodgdon have small rifle magnum primers listed, whereas Speer and Hornady have small rifle primers listed.
Any of you knowledgeable gents hazard a guess why, and for a case where the load is circa 17 grains of powder, would it make much difference in your opinion?
