Bkreutz Posted April 23, 2018 Share Posted April 23, 2018 I use the cheapest small pistol primers for 9 major, never had a problem, am north of 200K. Honestly don't think it makes a difference on a well sorted gun. Link to comment Share on other sites More sharing options...
B_RAD Posted September 30, 2018 Share Posted September 30, 2018 Bump this back up. To the gold using SRP, why those instead of SPP? Link to comment Share on other sites More sharing options...
chrisstophere Posted September 30, 2018 Share Posted September 30, 2018 I'm new to this division too but I believe it's because they are rated for higher pressures. Link to comment Share on other sites More sharing options...

What primer is everyone useing other than fed they are to hard to find. I've been running both Winchester small rifle and Federal small rifle primers. Equal success with both. Just make sure they are seated properly. Link to comment Share on other sites More sharing options...
rritchie82 Posted September 30, 2018 Share Posted September 30, 2018 WSR for me. I like CCI 500’s, but not the price. Link to comment Share on other sites More sharing options...

TONY BARONE Posted September 30, 2018 Share Posted September 30, 2018 (edited) Shot 50,000 Tula and Wolf primers thru one gun never a problem ran out of them and loaded Winchester small rifle that I had and encountered pitting around my firing pin hole at the breech face. Had to send the slide off to Clarks for breech face bushing repair great that they do that as it is a Matt McClearn open gun. CCI 400s now. Caught a bad batch of Winchester primers.

Some Open shooters use rifle primers because they're typically thicker and don't flatten as much with higher pressure loads, I on the other hand prefer to use pistol primers so I can see pressure signs as they develop and because anecdotally I believe they seal the primer pockets better preventing breech face erosion. I have never experienced breech face erosion on any of my pistols and have used SPP almost exclusively. Link to comment Share on other sites More sharing options...

OPENB Posted September 30, 2018 Share Posted September 30, 2018 Also, soft pistol primers can can crater and shave metal that can fill the firing pin channel and stick the pin. I'm splitting the difference and using Fed. SP Magnum primers in my open loads. I've read they are supposed to be identical to FSR in different packaging, but don't know for sure.

LilBunniFuFu Posted September 30, 2018 Share Posted September 30, 2018 Sellier and Bellot SRP, it's hard and cheap. CCI SRP if I am loading match ammo. Link to comment Share on other sites More sharing options...
OPENB Posted October 1, 2018 Share Posted October 1, 2018 S&B SR are hard as rock. They will not light off in eith if my open guns with 17# mainsprings. Love the pistol primers though. Fiocchi are a good value too in the 1500 to a box. Link to comment Share on other sites More sharing options...
snake32 Posted October 1, 2018 Share Posted October 1, 2018 I have used nothing but cci small rifle primers in my open guns. Im using VV n105 powder and have never had a problem with the primers. Link to comment Share on other sites More sharing options...

IHMSA15151 Posted October 1, 2018 Share Posted October 1, 2018 I used WSP in my Steel gun and had a bunch, so when I started loading for my Open gun to make major I tried them. Maybe it's my load but they seemed to flatten way to much for my liking so I switched to Fed. small rifle for my major loads. Link to comment Share on other sites More sharing options...
