Re: Low flash powder for .357 Mag
Stay with W231 or W540!! We did an extensive test years ago shooting combat out in Colorado Springs. We tested in a gun range that had Star loaders set up in 9mm, 38SPL, 357 mag, 38 Super, 44 mag, 45 ACP, and 45LC. All revolvers were 4" barrels with the exception of the 45Lc which was 6". The auto's were S&W 59, S&W 39 in 9mm, 38 SPL & 357 mag was S&W 10 & S&W 19 & Colt Python, 38 Super & 45 ACP were Colt Gov models. 45 LC was S&W 25 and 44 was S&W 29.
A lot of powders were tried and several factory loads. The absolute worst for flash was Federal 357 mag 158 gr JHP factory loads, they were blinding for 10' around!! Long story short, W 231 in everything but 45LC & 44 Mag. Those 2 won out with UNique for lowest flash and complete burn.
Obviously this was just a sampling of what was avaialble but just thought I would pass on our results.
