I don't know where else to post this, so I will try it here. 7.62x39 is unusual, it is one of the only cartridges that I have brass for with both Large & Small primers. I have always wondered about the pros and cons. Does anyone have any thoughts on what would be the advantage or disadvantage of 'one or the other'? All of the data I have in manuals lists Large Rifle Primers.
What benefits, if any, would I get from using the brass with Small Rifle Primers?
