    I'd suggest you look it up in a reloading book. They have all the loads which have proven to be within SAMMI specs.

    Its a .355 round so i imagine you could find reloading data for any weight bullet used in a 9mm. The 147 could be dicey because it takes up so much case space though.

    Lee 2nd edition lists up to 124gr. Might be able to find up to 147, but like Antihero said, I wouldn't try it.

    Even aside from the very limited space, it wouldn't shoot for crap.

    I have loaded some .380s with 115 grain JHP bullets. If you can find data for 125s, I think that would be about the heaviest reasonable to cram in the little round. Lyman goes to 115 jacketed and 121 cast.

    Would there even be room left for the powder? :p

    Would the bulged case even fit in the chamber?

    The inside of most all pistol cases are tapered and get progressively smaller as they get nearer the case head web.

    A heavy (long) bullet in the .380 case will protrude down into the taper and make the case wall pooch out. I imagine a 115 is about the best you can do with halfway good results.

    Remington Golden Saber 102 is factory loaded I believe. I'd guess that and the 90 gr. Speer Gold Dot are some of the best factory out there. If I were to go heavier, I'd use FMJ with the widest meplat that would feed.

    The heaviest I load is a SWC 105 grain from a lee mold hard cast and dropped in water to harden. The bullet is actually a .358" bullet. It's a very accurate and reliable bullet design. I size it to .357 inch and load with Bullseye to about 900 fps.
