Can't wait till this primer shortage is over with! So in my stash I have left about 7K of Small Pistol same for Small rifle primers, about 16K Large Pistol and a couple thousand large rifle primers. I shoot lots of small pistol. So I was wondering and I have read small rifle can be used in place of small pistol primers but there could be light strikes with certain guns.
So I took the chrono and old Phone I use that is bluetoothed to the chronograph to the range. I was trying to see if there is any difference shooting SR instead of SR. Not much, maybe 25fps faster.
