Giant81 Posted February 6, 2013 Share Posted February 6, 2013 As far as I know there is no problem at all using 38 (.357) bullets in a 9mm (.355/356) load at all but I thought it worth asking those that know more than I. I can't find any good 124gr .356 bullets but did happen to find a source of some 125gr .357 and figured I'd try those and see how they would work.

wgj3 Posted February 6, 2013 Share Posted February 6, 2013 I know some folk use the "oversize" bullets in super and SC, just have to be mindful of pressure, and could have some effect on accuracy, good or bad. Link to comment Share on other sites More sharing options...
Round_Gun_Shooter Posted February 6, 2013 Share Posted February 6, 2013 From my Sig 226 they work great, When I had a CZ Shadow, they worked great. S&W M&P did not like the same loads. The barrel did not stabilize the bullet so they tumbled. I now use 160gr Bayou sized 356 Link to comment Share on other sites More sharing options...
Hammar Posted February 6, 2013 Share Posted February 6, 2013 I have used the Montana gold 125 grain .357 bullets in my .356 barreled 38 super without any issues and with great accuracy. Link to comment Share on other sites More sharing options...
tambarika Posted February 6, 2013 Share Posted February 6, 2013 be careful with OAL. the .38 has a different profile than the 9mm. too long and the bullet will jam in the lands. Link to comment Share on other sites More sharing options...
rback Posted February 7, 2013 Share Posted February 7, 2013 (edited) I have had some success with Montana Gold 158 JHP in a Glock 17 using 3.6gr WSF and Win SPP at 1.12OAL. They shoot softer than 147gr and N320, but accuracy is poor. edit to add: I have mic'ed rounds from several different boxes of MG 158gr and they have all measured .356 Edited February 7, 2013 by rback Link to comment Share on other sites More sharing options...
Giant81 Posted February 7, 2013 Author Share Posted February 7, 2013 Anyone know if glocks (Gen 4 26) tend to be less or more tolerant to the slightly over-sized bullet? I'd think the rifling would be a bit more forgiving. Link to comment Share on other sites More sharing options...
rback Posted February 7, 2013 Share Posted February 7, 2013 I honestly do not know if Glocks are more tolerant to oversized bullets. I have however fired thousands of .356 lead 147gr downrange with no issues other than some minor leading just ahead of the throat(clean every 3-500 rounds). The lead in the MG 158gr is extremely soft, which is what gave me the idea in the first place. I was more concerned with finding a powder that wouldn't be compressed by the longer bullet than I was with the extra .001 diameter. Link to comment Share on other sites More sharing options...
