I have loaded my first 100 rounds of 40 S&W using small rifle primers (because thats all I had and they fit perfect) and have fired 10 of them so far that went through my glock 22 perfect. when i went to the reloading store today the guy there said "YOU DID WHAT?!?!" like I had just pulled a pin out of a live granade. but he has givin me bad advice in the past so I take what he says with a grain of salt. I have messured the firing caps of both the small rifle and the small pistol which I didnt have at the time but do now and they are exact down to the thousandth of an inch in length and width. my question is, are they the same primer just in a different box? He told me there was more pressure coming from the rifle primer and could damage my gun. any input would be nice.
