    Anybody have load data they could share with me? Specifically, I am looking for loads using a 124g Hornady XTP and Alliant Blue Dot. When I was doing my initial web "research", I found mention of Blue Dot as a go to to the SIG round. But, Alliant doesn't list the loads on their website anymore. Perhaps someone here has the actual Alliant data that they used to list?

    357 SIG 124 gr Hornady XTP 124 gr. and 800X

    I know you haven't ask for other powder data... but I have been playing with 800X for the last few weeks... while I haven't shot it over the chronograph yet I will this week if weather holds ... it does appear to be pretty dang fast and it is accurate too. Hodgdon only list one charge ... 10 grains compressed under a Speer GD 125 grain... I have tried it using the Hornady 124 124 gr XTP under that same charge and it shoots great. Since it is a compressed load... bullet set back is not a problem.

    I remember 800X being the uber powder for 10mm loaders, so I can see where it would be useful for the SIG round too. Have to try some out.

    Since we're talking about uber powders for the .357 Sig, AA#9 is supposed to be THE powder for .357 Sig. AA#9 is a dense ball powder that will fill the case and will also be slightly compressed preventing bullet setback. It also meters extremely well.;)

    AA9 doesn't seem to post the highest velocities. Since you mention metering, that was supposodly the Achille's heel of 800X. I remember reading guys posting about 10mm loads that were hand measuring pretty much each charge because it metered so poorly. Never tried the stuff myself.

    800-X does meter poorly because it's a very large flaked powder. Many reloaders weigh each charge to overcome the poor metering characteristics. THE load for a 124 gr. JHP with AA#9 is 13.0 grains max. You won't get as much muzzle blast either as compared to Blue Dot.;)

    Chuck,

    This information is from Hodgdon #27 manual. Bullet is the 124gr Hornady HP/XTP:

    List one load only--Primer-Federal #100, C.O.L.=1.195", 10.6gr--1405 fps--36,900 psi.

    Hope this helps.

    Thanks for the info. This is my first can of Blue Dot, never played with it before. I read many reports of huge muzzle flashes, which is what sold me on it :evil:
    Bob, thanks for the data. Soon as my Graff's order shows up I can start putting some loads together.
