Hi-Power Jack Posted July 15, 2009 Share Posted July 15, 2009 While waiting for my Wolf primers from PV (Just saw the note, so I'm hoping my 20,000 come in next week:) - I bought 5,000 S & B primers. Just tried 18 of them in developing a 9mm major load with HS6 powder and 115 gr MG JHP's. Nine (one-half) of the rounds did NOT go Bang the first time - they all went Bang the second time. I've Never had that happen with any WW primers. Since I have 5000 of these beauties, wondering if I can get a more powerful hammer spring? Is that safe, advisable in an STI TruBor? Would it make the primers go bang? Would I have to replace the spring when I went back to the Wolf primers? Thanks, Jack Link to comment Share on other sites More sharing options...
Steve J Posted July 15, 2009 Share Posted July 15, 2009 Either a stronger hammer spring or seat the primers better. Link to comment Share on other sites More sharing options...
GTOSHootr Posted July 16, 2009 Share Posted July 16, 2009 I was going to post a question as to whether people have had the same experience with the S&Bs. I tried 100 of them in Supercomp and had 4 not go off. Much better than you experienced but ruled them out in my book for match use, they'll be for practice only. Mine were seated deep on my 1050 and my mainspring is light (16# or 17#?). Link to comment Share on other sites More sharing options...
Duane Thomas Posted July 16, 2009 Share Posted July 16, 2009 The S&B primers are notoriously hard. Okay for guns running full-power hammer springs, not so good for a gun running a tuned action. Link to comment Share on other sites More sharing options...
Steve J Posted July 16, 2009 Share Posted July 16, 2009 They probably need at least a 18 or 19# mainspring. Link to comment Share on other sites More sharing options...
Hi-Power Jack Posted July 16, 2009 Author Share Posted July 16, 2009 They probably need at least a 18 or 19# mainspring. If I used a 19# mainspring, would that work okay with standard (WW or Wolf) primers, or would I have to re-replace the springs again? Jack Link to comment Share on other sites More sharing options...

Jack I use an 18# spring with a low mass hammer and have 100% solid primer strikes with even the hardest. There are other variables at play that may make your situation different, probably won't, but it's something to me aware of. Unreliable ignition can also be influenced by a worn or broken firing pin, ultra low mass hammer, sticky, rough, dirty mainspring housing tunnel.

Unreliable ignition can also be influenced by a worn or broken firing pin, ultra low mass hammer, sticky, rough, dirty mainspring housing tunnel. My gun is clean, so it can't be the housing tunnel, and a gunsmith just checked it over so it shouldn't be a worn or broken firing pin - the hammer is stock STI TruBor hammer, and works well with my WW primers (Never a misfire). I'll check into an 18 lb spring, and see if that works. Thanks for the help. Jack Link to comment Share on other sites More sharing options...
Hannu Posted November 14, 2009 Share Posted November 14, 2009 Where you buy S&B primers in USA ? SPM was my favorite 9mm Major-primer - no problems (about 20k used) with extended firing pin, DK hammer + 17 lbs spring. Link to comment Share on other sites More sharing options...

Thanks, Jack I have a Glock with a tuned trigger that will not ignite Muron primers for the most part. As far as I know Muron are sold in the US as Wolf. On the other hand I never had any problem with S&B factory rounds. Asuming the the primers in the factory rounds and the one sold as primers are same/similar they should work better than the Wolf Link to comment Share on other sites More sharing options...
Quigley Posted November 23, 2009 Share Posted November 23, 2009 I switch back between Winchester and S&B small pistol primers (9 Major) with my Bedel blaster with zero problems... I can't tell the difference... Link to comment Share on other sites More sharing options...
