    Hello all,
    I picked up a new S&W 340M&P earlier in the week. So far the only defensive loads that I have shot are the DPX 110 grain +P.38spl and Speer GDHP +P 135 grain in .38 spl. Out of the two, I prefer the DPX because they seem more accurate in my new revolver. They are both a little peppy but controllable.
    Has anyone compared the .357 mag versions of the DPX and short barrel GDHP out of a light weight gun? Could you share how they compare in terms of recoil and muzzle blast? I tried some full power 125 grain loads and they were no fun to shoot at all.
  2. i would be interested also. i carry Speer GDSB .357 out of my S&W j frame 640. so far i think its the best balance of power/controlability and bullet design. the DPX is the only other ammo i would want to look at.

  3. You also may want to try Hornady's .357mag/125gr FTX ammo.

    It's not .357 Mag but I picked up some 125gr .38 Special XTP. Seems fairly controllable but I didn't like the results from this test:

    I'll probably go with the GDSB.

    Personally I still don't see the appeal of a Magnum in a 2 or even 3 inch barrel. Velocity loss is extreme and you basically are just shooting .38 Special +P, from what I have seen in chrono tests.

  5. when i tested different .357 magnum 125grn in my j frame i would get anywhere from 1150 to under 1200fps with a heck of a lot of blast. the speer GD Short Barrel 135grn .357 magnum ran a little over 1000fps from a 2 1/8'' barrel and felt and shot like a real hot 38.

    I'm looking at different very hot .38 loads and very mild .357 loads. I have no desire to shoot stout magmun loads in this gun.
  7. if that is what you are looking for the .357 magnum Gold Dot Short Barrel is just the ticket in a steel j frame. i don't know about some of the light weight models though. its probably one of the lightest magnum loads.
