    It sure is a good shoot'n smooth revolver. I have the 6" model. I was testing some Double Tap SD ammo, which is very good ammo, and had a question for those more knowledgeable about .357 Mag than me. I love their 10MM in my converted G21 by the way. Any way, they seem to have a couple of good SD sizes:125 Gr. SJHP at 1605 fps. and 158Gr. SJHP at 1410 fps. Both are from a 4" barreled gun.

    I know on my j-frame 340 that you should avoid the 125s as they can promote faster forcing cone wear, would that be the same for the 686? I really can't see shooting either one regularly as I will just use them for SD. I have been practicing with GA 38 Spcl. 125Gr. at 950 fps and they seem the ideal round to practice with. But they are the 125s and I am concerned about premature forcing cone erosion.

    So anybody have a good opinion on all this?

    Thanks,
    Gary

    The Forcing cone and general construction of the L frames like the 686 was designed specifically to overcome durability issues suffered by the lighter K frame using 125gr full powered ammo, so you should be fine there.

    It was my understanding that with the Scandium frames you didn't want to load too light of a bullet in .357 mag because the recoil is so violent the lighter bullets (read shorter, less neck tension) have a greater tendency to jump their crimp and potentially lock up the gun. If you can shoot enough mag loads from your 340 to damage the forcing cones, you are a better man than I. Hated my 360 and full house loads.


    Shoot whatever the heck you like out of the 686.

    Zombie Steve,

    I hear ya. I have only shot a handful of magnum loads in my 340, not fun at all! I carry GA .38 Spcl +P they shoot real nice in the j-frames. I can make a head shot at about 30 feet, real controllable ammo.
