Fred63 Posted July 6, 2016 Share Posted July 6, 2016 Loading 9 mm at 175 pf and did my testing with Fed SPP. I'm happy pressure is ok but would like to go to SRP as I believe they contain pressure better, I have tried Rem 71/2 SR Benchrest but had 3 /100 fail to ignite. I've found a lot of conflicting rankings on internet and would appreciate your first hand experience about hard/soft and ignition rate with what brand / type you have found works best.

Hi-Power Jack Posted July 6, 2016 Share Posted July 6, 2016 I haven't had any trouble with the WW Link to comment Share on other sites More sharing options...
Mark R Posted July 6, 2016 Share Posted July 6, 2016 I've had 1 misfire in about 10k of CCI SRP...and because I put the primer in backwards and didn't inspect after reloading...duh. Link to comment Share on other sites More sharing options...
rdinga Posted July 6, 2016 Share Posted July 6, 2016 Federals are indeed the softest primer. However I prefer CCI primers to other brands. Never had a failure to fire with CCI primers. Link to comment Share on other sites More sharing options...
RiggerJJ Posted July 6, 2016 Share Posted July 6, 2016 SRPs will contain pressure "better"? How so? Imho a rifle primer in a pistol will hide pressure signs, and can cause flame cutting on the breachface because they don't seal as well as pistol primers with the lower pressures in pistols. If you have a good load with pistol primers, why change what is working? I would continue to use pistol primers...I use win spp...even thou I have many rifle primers... jj Link to comment Share on other sites More sharing options...

rustybayonet Posted July 6, 2016 Share Posted July 6, 2016 I shoot M&P's and never had a problem with:fed, win, s&b and cci. They are what I have used. S&B's have some loading issues but not firing Link to comment Share on other sites More sharing options...
Out of Ammo Posted July 6, 2016 Share Posted July 6, 2016 I've had problems with light strikes when using S&B. I've used CCI, but prefer WSP as they are consistently easier to load on my Dillon and they always go "bang". Link to comment Share on other sites More sharing options...

It was really obvious. It was more than enough to make my mind up on which primer to use in my 9 major gun. The guys using rifle primers were really proud, kinda like they were really being macho for using rifle primers...A primer is a primer. They all do the same thing, ignite the powder. Using a rifle primer with 7-9 gns of powder that is designed for 24gns or more is an overkill and unnecessary. Couple that with harder cups that don't seal in the pocket and cause flame cutting on the breachface, and no appreciable velocity difference or general advantage...well, seems to me that the answer is obvious...

dansedgli Posted July 6, 2016 Share Posted July 6, 2016 Fed srps work good for me. I bought 5000 remingtons and had issues with light strikes. I put an extended firing pin and a 19lb mainspring in which cured it. It cost about $20 and I'd be confident using the rems in matches now. I didn't notice a difference in how the gun handled so ill leave it like that. Link to comment Share on other sites More sharing options...

Fred63 Posted July 7, 2016 Author Share Posted July 7, 2016 Not saying srp are better, it may mean I don't have to explain my slightly flattened primers to well meaning critics who don't believe in loading outside published data every time I shoot. As above I did all my testing with Fed spp so as to get real indcation of pressure. Unfortunately I just picked the hardest srp ( Rem 7 1/2 ) to try. Will possibly try Fed srp next.

Dr Mitch Posted July 7, 2016 Share Posted July 7, 2016 Best quality I have had have come from CCI. Federal has been better than Remington and Winchester. I feel Tula primers are on par with Federal. Quality meaning number of bad primers per case. All SRPs. Link to comment Share on other sites More sharing options...

Jmho jj Nothing macho about using rifle primers! lol and locally I haven't heard or seen any of the open guys having problems with SRP. Only guys I know for sure who use SPP are infinity guys because they get told to use them. Link to comment Share on other sites More sharing options...
Fred63 Posted July 7, 2016 Author Share Posted July 7, 2016 Didn't mean to start this debate all over again, just wanted advice on what's not too hard to fire reliably but hard enough to not to deform much. Gun is czechmate so should have average firing pin force etc. please only those using srp give advice. Link to comment Share on other sites More sharing options...
Steve RA Posted July 7, 2016 Share Posted July 7, 2016 I use Tula SRPs in 9mm, small primer .45s and .223 and have no trouble with them - other than you can't get them anymore. Link to comment Share on other sites More sharing options...
lesm Posted July 7, 2016 Share Posted July 7, 2016 I don't shoot too many rifle primers in pistols, however I have shot a fair number of Federal small rifle primers in 38 super and they punch pretty easily. Small pistol magnum's might be of help but I have never heard a definitive report on the relative hardness of their cups. Link to comment Share on other sites More sharing options...
jcc7x7 Posted July 7, 2016 Share Posted July 7, 2016 Fed srp's soft,good sd & es , no erosion I use them for everything major& minor ,win when I can't get fed CCI always good just more money in my area S&b but spp Soft to hard list Link to comment Share on other sites More sharing options...

Quality meaning number of bad primers per case. All SRPs. So than quality varies with brands. I have been using CCI and until this last batch, have not had problems. But batch e29xxx has been very bad. Like 20% bad. But, I bought an other box of the CCI to see how it goes and so far so good. If I have 1 problem with the new batch, I change brands.

mlmiller1 Posted July 10, 2016 Share Posted July 10, 2016 We have been using s&b but have had a terrible batch this last box. 1 stage had 8 fail to fire. No they arent high primers. 1 of the 8 fired on a restrike. We have loaded several thou of these no problems until now. Back to winchesters.

Boxer1 Posted July 12, 2016 Share Posted July 12, 2016 The S&B and Tula/Wolf Primers are some of the hardest I have ever tried to use. I have loaded 9 Major with SRP Fed and CCI. Also what about a Magnum SPP that should have a thicker cup. Link to comment Share on other sites More sharing options...
Maximis228 Posted July 12, 2016 Share Posted July 12, 2016 100K CCI 500's running in 9 major for the last 2.5 years. Not a single issue. Link to comment Share on other sites More sharing options...
