Last time I was at the AGC pistol range I did my usual scavenging for brass (looking for 45 ACP in particular) and picked up some 45 ACP with small pistol primers. This was new to me as I have always hand loaded using large pistol primers. When and why did the SP primer thing start and where can I find load data using the SP primers in 45 ACP? Are the small primers magnum or standard?
