Has Underwood fixed the 357Sig velocity issue?

    ?????????

    Read a while back on here where someone chrono'd the 125gr GD load from Underwood and it was waaayyy short of the 1450fps advertised (like low 1300's IIRC).

    Maybe Underwood can chime in? If it has been rectified, how do we know we aren't going to get old substandard (velocity-wise) stock left over?

    I guess that their quality control are the users with chronographs!!

    100fps wouldn't freak me out too much, given the range of temperatures, guns (chamber/bore variances) and other factors. I've seen the stuff deliver, exceed and sometimes fall short, just like other brands.

    I see ~ 100fps as quite a variance, especially when they are achieving it with other calibers like 9mm, and 357Sig is all about velocity.

    YMMV.

    I don't know. But if it were some kind of short-barrelled hideaway pistol, that would account for the low velocity.

    They were out of the office until tomorrow when I tried to call earlier. FWIW the 357Sig 125gr was listed as "Out of Stock", so maybe they pulled them or are rebooting for the next batch? :dunno:

    I've seen a few examples of it chrono'ing at low 1,300s to about 1,380fps from 4" barrels.

    Heck, they are getting 1,300fps from their 124gr 9mm +p+ loads in 4" barrels. There has to be an issue with it.

    I did read that Underwood used a G31 for their 357 sig testing.

    Yes, they were coming up short. That has been addressed, along with an increase in velocity to 1475FPS out of a 4" barrel. For a couple weeks they've been manufactured this way with more on schedule for production late this week.

    I do still wonder why the Sig is loaded so lightly to where the 9mm is almost the same in velocity.

    It sounds like a simple mistake at the factory. :shocked:

    At 1,475fps out of a 4" barrel the new loading is 175fps faster than the 9mm 124gr +p+ loading. Out of my G24 with a 6" barrel that load will be smokin':smoking:

    I think that if they paid the same amount of attention to the Sig as they do the 9, as far as developing the load, we'd see a significant difference, as we should.

    I'd like to see TNOutdoors9 test this load out of a 4" barrel. I think (not sure) that 1,475fps is at or slightly exceeding the upper velocity limit of the GD.

    For my G24 I have loaded it up with 125gr GDs (1,350fps variety). I think at ~1,600fps that thing will start to break up. I could be wrong.

    I wonder how your loads would work in a G17?
