6.7gr under a 230gr plated @ 1.250 = 940fps

Howdy, just got back from the range and came across something ive never seen. I didnt bring the chrono so no raw data this time, but conditions were -10 to -15 F (pretty darn cold to shoot outside). My standard loadout for 45acp is usualy 7.5gr of longshot under a 230 heavy plated, which chronos in around 950-975 at 30 deg F. I experienced a ton of unburnt powder at these negative temps, so much that the rounds in the magazine were covered in unburnt powder. I also had still burning powder flying out with brass when it ejected. This was only on my 1911 5in, my 3.3in xds just had a huge fireball when i shot it. Just wondering if anyone has issues like such with longshot? My other rounds were with unique and they shot great like usual.

What kind of FPS did you see? Been doing the max load from there website and felt snappy but 8.2 is a ton lol, its this a full case @ 8.2gn?

Update! Made it out to the range to use the new Winchester Super-Handicap AA powder with 9mm and 45acp loads, 9mm - 115gn plated / cci primers - 4.25in barrel M&P / 1.120OAL 3.6gn - 800 / 799 / 849fps - Stove pipe 4gn - 960 / 930 / 964 - soft 4.5gn - 980 / 1033 / 990 - felt good but not stout for 9mm - In comparison i was also shooting 5.5gn Unique with same bullet at 1280ish fps 45acp - 230gn plated / Remington primers - 5in para 1911 / 1.250OAL 4.4gn - 739 / 761 / 736fps 5gn - 745 / 760 / 745fps 5.2gn - 844 / 799 / 801fps - Chrono'd the same as box PMC Chrono was a Prochrono digital , conditions were 31deg and overcast. The 5.2gn load is a nice soft loadout that would be great for plinking, i did not test accuracy other than trying to not blast my chrono lol Hope this helps, just remember this is my experience and is in no way any sort of recommendation for load data!

Will do, should make it to the range to run a few new loads through the chrono and will upload some data.

I grabbed some as well by mistake too, but i grabbed 2 lbs lol. I found some info regarding 9mm and some 45 around here. Loaded a few up in a ladder spred, just have not made it to the range to chrono them. It looks like if its a good powder, it will meter well, similar to longshot, just finer grained.
