    I'm about to acquire a S&W 340 PD and was looking to start reloading for it. This will be my first revolver and first time reloading for it. I was thinking of loading .38 +P for it and was looking for some recommendations. What types of powders would you want to use for this extremely short barrel? I was thinking of using a Hornady 125 gr. XTP bullet. Thanks for the imput from you seasoned folks.

    I use ~6gr of PowerPistol under a 135gr ShortBarrel Gold Dot for a good +P load. The 13th Speer book has some good max and +P loads for 125 and 158gr .38 SPL.

    The older reloading manuals used to provide specific, higher charged load data for the subnose revolvers as their short barrels do not contain the bullet long enough to generate the higher pressure such a load would develops in standard length barrels.

    Checking Speer #8, maximum loads for K or similar medium framed revolvers with 2" barrels using a 125 gr Speer SP:
    13.5gr 2400, 1070fps w/ CCI 550 magnum primer
    7.0gr Unique, 1003fps
    11.0gr SR4756, 1148fps
    9.0gr AL-7, 993fps

    I don't believe you'll find the last powder around, and it is very possible that the current production of 2400 and Unique will produce different pressures from what was being produced with those powder formulations in 1970.

    As always, take the necessary precautions when working up loads in YOUR firearms.

    The muzzle blast will be fierce w/ PP. I like Unique or WSF in a short snub bbl. IT won't give you top vel, slower powders always will, but it is a good balance of vel & blast. With 9gr of Unique under a Rem 125grSJHP, I can get 1230fps in my 2 1/4" SP101.

    I don't find it to be all that bad, really. Of course, I don't shoot extended range sessions with it...

    While I haven't used PP in 38, I have used it a bit in 9mm in a 3.1" LC9. It was a bit louder than other powders, but it wasn't like I expected it to be. It was nothing like WW296 or Blue Dot and a 125 in 357 mag.

    Thanks for the info Fred, I just bought the same snubbie today, I was tempted to get the 3" but felt the hammerless 2 1/4" would fulfill my needs/wants better.

    Need to get some reloading supplies. I put 50 rounds through today of American Eagle 158gr JSP, nice shooting pistol, but need to break in the DA trigger some.

    If you're looking for a SD round for a 2 or 2 plus inch barred gun just pop in some 158grain LSWCHP +P's.

    Lot of anti-personnel history with that round and almost all of it good.

    (It won't penetrate a car door if it hits an internal support though. :whistling:)

    Funny you mention this as I was just looking on Missouri Bullet's website and they have some 158gr bullets at a good price.....

    I'm still trying to grasp the thought that reloading 357 magnum will be about the same cost as 9mm, lol........
     
  13. Probably cheaper. You dump the .357 where you want. My G26 tosses it behind my shoulder, but my wife's LC9 send the brass into orbit.

    Yep, all pistol rounds from 380 to 45colt can ber reloaded for about the same price, bullet cost varying. Powder charges are close, prmers identical. I started reloading the 38sp/357mag. Even way back then, one could reload 357mags for about 1/3 the cost of factory. Today loading w/ commercial cast vs 9mm FMJ, you can reload 357mag for just a bit less than 9mm.:supergrin:

    If I had a snub-nosed .38 revolver, I'd load standard pressure loads using 200-grain Jead bullets. Out of the 2-inch barrel, they are understabilized, and tend to TUMBLE upon impact. These bullets are hard to find, but I believe that Winchester still makes them.
