Reload for 9mm?


January 4, 2012, 07:07 PM
Has anyone ever, and/or should/could, .38/.357 LSWC which is .357, be used for 9mm luger which is .355? Just speculating. Would they feed? Would they create too much chamber pressure? Would they overly lead-up the barrel?

By the way, these are pulled bullets.

Some input please!

I think the first problem would be flaring the brass enough to seat a .003 in oversize bullet as most 357 lead bullets are .358. The next problem would after seating the bullet there would be very little room left for powder so choice for powder could be tricky. Next problem would a lswc feed and the most scarey is would you blow up the gun trying to force it down the barrel. I sure wouldn't try it.

.357" jacketed and up to .359" cast in 9x19?; no problem for me and my pistols. First step if you wish to pursue this might be to see what your gun slugs, and see how that relates to the chamber and throat. It is very common for many 9mm pistols (mainly euro made/branded) to have groove diameters of one, two, or even a bit more thousandths over the SAAMI .3555" spec. My two pistols have groove diameters of .3572" and .3578" (when new), generous chambers and throats, and my standard sizing diameter for cast bullets I make and buy is .358" w/zero chambering issues.

Fitting the bullet to the barrel for best accuracy/lack of leading works the same as any other caliber, and why it seems so taboo for many concerning 9mm handguns makes no sense. Proper loading as with any caliber is always key, and has served me very well using cast and jacketed bullets on the 'fat' side from 95 grain LRN, to 158 grain '.38 special' LSWC's, with perfect functioning. Good luck.

Galil5.56 hit the nail on the head. My Ruger measures 0.3561 and I have to use at least 0.357" lead bullets for good results. I am putting the the Precision Delta 124 grain 38 super bullets in my 9mm pistol now. These measure at 0.356" diameter, same as normal lead. The Penn Bullets web site has information on 9mm sizing, indicating it's not uncommon to load 9mm with 0.357 or even 0.358" bullets.

Thanks Guys! But I remembered that my bullets were 158gr LSWC, and I think that might be just a tad heavy (read "long") to get enough powder in the case to even push it out of the barrel. Oh well, it was just an idea on how to use up some bullets and "Bulls-eye" powder.

Actually, lead 9mm bullets are usually sized to .356" so if you buy 38/357 bullets that are sized to .357" you are only .001" over the common size. I don't see that as a problem.

I shoot .358" 158 gr LSWC and .357" 158 gr JHP in 380, 9x19mm, and 9x23mm.

I like Power pistol for powder.

I have done it. It can work. Not how I normally load 9MM though.
