I stopped at Cabela's in Reno yesterday and was drawn to the counter where the primers were located. No surprise that there wasn't any deals being offered but, my observations brought up this question. They offered CCI small rifle benchrest primers for $155/1000. There were also Winchester #41 small rifle primers for $79/1000. I've used these #41 primers previously with no problems. My question is "What exactly is a #41 primer and how is it different from a regular small rifle primer?" I used to use CCI small rifle benchrest primers. I didn't know what the difference was in them over a regular primers. Can anyone explain it to me?
