[QUOTE="Teri Anne, post: 2596466, member: 118816"] Well now you have me a bit confused, which at my age is somewhat difficult to do. I have been loading .308 since about 1970 and all of the brass I have come across for the .308 uses Large Rifle Primers. I have never run across any .308 cases with Small Rifle Primers. First of all, where did you find them? Secondly why outside of primer availability would you want to use small primers in a cartridge designed for large primers. There has to be a big difference in flame propagation between the two thus burn rate and pressure differences which would affect bullet velocity. Over the years I have found that using Magnum primers in virtually everything I load works well. Of course I work up the loads from scratch, using the minimum velocity from the loading chart and have not noticed any real changes in velocity or pressures even when working at the top end of the loading chart. I have had people tell me I am crazy, and to be honest probably all of us are, but this crazy old lady is not afraid to experiment but does do it carefully. In closing, what advantage is there to using small rifle primers in a cartridge designed for large rifle outside of primer availability which while yet is somewhat of a challenge they are pretty much available these days, Oh, yeah I forgot.Magnum primers are pretty well available, not so much any of the specialty type primers.
