    Anyone chronograph the Speer 135grain .38+P Gold Dot fired from a 4" barrel?

    yes. From a 686-4", five shots averaged 1014 fps. Those were shot in October 2007, and a bigger ES was noted; I haven't transcribed the range notes. FWIW, that average drops nicely under the nominal 1050 fps max velocity Speer recommends for this bullet.

    Thanks for the fast replies guys!

    What I'm looking for is a faster .38 special load out of my 4" K-frame. I'm having trouble finding these:

    But I just stumbled upon this 125 grain load from Buffalo Bore:

    http://www.buffalobore.com/index.php?l=product_detail&p=109

    a. S&W mod 60, 2 inch- 1072 fps (319 ft. lbs.)
    b. S&W mod 66, 2.5 inch- 1108 fps (341 ft. lbs.)
    c. Ruger SP101, 3 inch- 1180 fps (386 ft. lbs.)
    d. S&W Mt. Gun, 4 inch- 1258 fps (439 ft. lbs.)

    Which looks like mid range .357 velocities from a 4" barrel! I'm just concerned that the "low velocity expansion" hollow point will explode when it hits something because it's moving too fast. What do you think?

    I would not worry about that with a quality Speer Gold Dot with a delta V of only about 125fps vs. a 2.5" gun. It's just not enough difference to cause worry. Out of a Carbine or something, I might wonder about it.

    Actually, Speer has (or had) the same concern that RatDrall has. The Speer white paper for their "short barrel" GD bullet established a nominal range of 860-1050 fps. Beyond that, the bullet is / was liable to fragment. That was for the original 135-gr. I have a pdf copy of the white paper on that; if you want a copy, e-mail me.

    However, IIRC, Speer 'redesigned' their GDHB bullets last year to drop the minimal velocity required--anyone have a link to that info? I think they now claim it will at least start to expand below 800 fps. And, I do not recall if they have tweaked their specs for the different bullet weights....

    So, if any one has any links, chime in, please.
