    If I had a lifetime supply of those, I'd just keep using them too!

    Hey rev, if you're ever driving through Waco, bring containers labeled with each of the above. I'll share with you.

    This is probably dated, I don’t see BE-86:

    I switched to Power Pistol for a medium rate powder during the ammo panic and am quite happy in .38 +P.

    You want BE-86. A friend of mine is a factory sponsored shooter (big name starting with f) and his sponsor and a lot of others load it in their factory loads. He said "at least I'm pretty sure" with a big smile. It's only new as canister powder. It's been used by several factories for years.

    It's reasonably priced, extremely versatile, flash suppressed, meters well, and seems pretty clean. I've went through about 2lbs of it so far in 9mm. I plan on it being my primary pistol powder in .380, .38SP, 9mm and .45 and switching to Sport Pistol specifically for USPSA ammo.

In the 44 there is some really nice data pushing a 240 pill at low-recoil 44 special velocities ~6.5. In my 44 Mag Snubbie (Alaskan) I had to boost it to 7gr but it is still really soft. It is a nicely metering, non-temp affected powder that burns reasonably clean. Try 3.5gr under a 147 coated in 9mm sometime for a super nice action pistol load.

    My testing with Win 231 (and WST) showed a distinct ‘reverse’ temperature sensitivity: http://www.doodieproject.com/index.p...-5#entry156400

    9mm
    Winchester 231 (aka HP-38)
    135 gr Bayou Bullet - Hitek Coated
    Federal Small Pistol Primers
    1.090-1.100 COAL
    EAA/Tanfoglio Stock 2 - 4.5" Barrel, Polygonal rifling

    3.5 gr 911 fps, 122 PF
    3.6 gr 957, 129 pf
    3.7, 980, 971, 131-132 pf
    3.8, 989, 992, 133 pf
    3.9 1007, 135 pf

    10 rounds @ ~72F: Lo 994, Hi 1039 (Flyer), Avg 1004, E.S. 43

    8 rounds heated on oil heater - avg 972.5, 131 PF
    10 rounds from chest freezer - avg 1017, 137 PF. 3 'hot' rounds at 1032, 1041, 1042 fps.

    WTF? Win WST AND Win 231 are both reverse temp sensitive? Who'da thunk it....

    This powder seems a little more manageable than WST but is definitely showing primer flattening at 138 PF. Less at 131-134 PF.

    I guess if you are Leadchucker and shoot in a predictable climate that this could be a good choice.

    I know we've gone back and forth over this before: https://pistol-forum.com/showthread....-bullets/page2

    I tested Win231 at 40F, 70F, 90F while you tested at more extreme temperatures.

    Working with a 135PF load (which is a good margin of safety for Action pistol) I think you saw a +-3PF variation with Win231.
    This was contrast to my experience where there was no measurable difference.

    Enos has a few threads about Win231/HP38 https://forums.brianenos.com/topic/2...e-sensitivity/

    The reality, however, is that Win231 is a nice broad-use powder that, with a respectable PF loading should make it at all reasonable temperature spreads.

    It's the same burn rate as PP.

    I’m good at figuring things out, but memory isn’t my long suit.
