    Pappy,

    I reckon it will boil down to the powder and barrel length. The 158 will, all things being equal develop more velocity, but the energy of the 180 at somewhat lower velocities can't be discounted. What are your plans for this powerful load? A heavier bullet will, usually promote more recoil with equivalent powder throws, as compared to the 158.

    Pappy,
    What will be the composition of the bullets you'll be using. 158 grain is the "Standard" you can shot just about any 158 bullet design thru either of those revolvers. The 180 grain sounds like a hardcast bear load. Am I calling it right? The 180 is going to have a slower bullet speed, but it'll have a whole bunch of knockdown power for sure. Like MMitch said there will also be a noticeable step up in recoil with the 180 as well.
    If you're looking for a woods carry round in big bear country, the 180 would be an excellent choice.
    If you're looking for home defense, a 158 grain JHP is ideal for that purpose.

    Let us know the intent, and we'll probably give a bit more advise or fresh comments.

    Regards,
    Gregory

    Pappy,

    The 158 gr. jacketed bullet is what unlocked the potential of the 357 back when it was introduced. The jacket allowed higher bullet velocities without leading. The length of the 158 gr. bullet didn't wear out the forcing cones as quickly as shorter bullets. Being a traditionalist, I'd have to go with the 158 gr JHP for a 357. Especially in a light 4" revolver.

    Very good comments above pappy. If you reload, you can customize your load to do about anything, but, accuracy should be your guide in the final bullet selection. You may even want to split the difference and go with a Keith style 172 gr. cast bullet and have the best of both worlds.

    Oh sure, Mick. Way to muddy the waters.

    You will find much greater variety in the 158 grain offering. Jacketed, semi-jacketed, lead, etc. also bullet design like semiwadcutter, round nose, truncated cone, lead hollow point, jacketed hp, etc.

    Wait, what was the question again?

    If it were me, I won't consider a .357, regardless of loading, even approaching adequate for protection from bears. That said, I would reserve the 180 grain loads for large frame .357 magnums the same way I would limit M29's and 629's to 250 grain loads. These guns were never designed for these heavier than "standard" bullet weights and there is more to consider than just the chamber pressures.

    Not sure ....but, doesn't Buffalo Bore offer a 180 Gr cartridge in .357? It'll probably be a handful! But, if that's the gun you own.......that's the gun that you have with you. It might be a good idea to put on Pachmyer rubber grips! Bob
