joeskato Posted April 30, 2012 Share Posted April 30, 2012 (edited) sorry for bumping an old topic... wonder if sealing the primer would help with this? I am running into this issue as well. Edited April 30, 2012 by joeskato Link to comment Share on other sites More sharing options...
GrumpyOne Posted April 30, 2012 Share Posted April 30, 2012 My new S&W M&P 9Pro is experiencing the same problem, the breech face is eroding after less than 2000 rounds of mainly factory PMC ammo. I've shot a handful of reloads in it but don't think I should be seeing this on such a new gun... What to do?? Are you sure it's eroding? Drag a needle across the face and see if it "catches" on the ring. Sometimes that ring is nothing more than a carbon build up. Cotton swab with alcohol across the breech face will also let you know. Scrub it and see if it comes off... Link to comment Share on other sites More sharing options...
DyNo! Posted May 1, 2012 Share Posted May 1, 2012 "Primer seal" is to keep moisture out and will not retain high pressure gas (X0,000 PSI). Link to comment Share on other sites More sharing options...
joeskato Posted May 1, 2012 Share Posted May 1, 2012 "Primer seal" is to keep moisture out and will not retain high pressure gas (X0,000 PSI). have you tested this? i don't think it has to retain x0,000 pressure gas, just has to help the primer seal.

Nope, but nail polish remover is pretty cheap and would be used more in industrial applications to plug leaks if that was all it took. Edited May 1, 2012 by DyNo!

What does nail polish remover have to do with anything? You've never heard of high pressure gaskets in industrial applications before? It's not like it has to stand the test of time, just one cycle. Anyone with USEFUL information have anything to add? Link to comment Share on other sites More sharing options...

rhyrlik Posted June 23, 2012 Share Posted June 23, 2012 I loaded up some 9mm with a light load of Longshot and FC-200 primers from the old red box. I got primer leakage. Your erosion theory is plausible. Link to comment Share on other sites More sharing options...
