    I've been threatening for months to do my own fotografy of the muzzleflash of various factory and reloads. Here are the first results.

    I used my 3 Glocks, a model 37 in .45GAP, a model 20SF with 5.15" LW barrel in 10mm, and a model 32 with LW 4.5" barrel in 357SIG. The pistols were shot from a rest and fotografed in the dark. I used the same shutter speed (2 seconds), lens opening (F4), and ISO rating (100) for all shots. I fotografed 10' away from the pistols.

    The only factory loads I had were for the 357SIG.

    The clear winner here is the Speer, with the Winchester a close second. (This Winchester load is the same one that achieved the highest velocity of any 124/125g. factory load I've measured.) Fiocchi clearly did NOT select the powder they used for low muzzleflash, and I would not want to shoot that in the dark while wanting to see anything afterward.

    I shot 2 reloads using Universal or Super Field in .45GAP.

    These 2 tied, which surprised me, as Universal was the powder that had NO MF based on prior tests by the Phoenix Police Department*. I would used either of these powders in my PD loads.

    I'll be doing more testing; this trip was my 1st attempt at fotografing MF, and I've learned a few things.

    I hope these pics help you select PD ammo or powders for your PD loads. I know that I'm satisfied with my choice of A9 in my 10mm, Universal in my .45GAP, and Speer GDLE 125s in my 357SIG.

    Pls see my next message...

    ...for results with the 10mm.

    Good to know. How do you think your loads with 800-x compare with the factory 357s?

    If you mean velocity, the Fiocchi is lowest at a bit over 1300FPS at 10', the GDLE125 runs about 1360, while the Winchester is fastest at a bit over 1400. My 800X load would run about 1275FPS.

    I'll be redoing these with better fotografy, and I'll be better prepared, with about-equal-power loads and more of them including with A7 and A5.

    Yes indeed, but replacing the idiotic 'f' sound of 'ph' is one of my campaigns to increase the quality of written English. Getting rid of the equally idiotic 'gh' nonsound is another, which is why I white 'tho' and 'altho'.

    I was referring to the flash but I see you listed it in thread #2, I'll be interested to see those. I plan to start loading with 800-x powder in the next 2 to 3 weeks....unless you change my mind.
