BE-86 ... upside was no muzzle flash... both Unique and W231 give off a fair amount of muzzle flash in the 4" barrel, and I'm trying to get away from that.
In my testing, BE-86 actually produced larger and brighter muzzle flash than W231/HP-38 (W231/HP-38 was near max load and BE-86 was medium load and perhaps why Alliant had to add flash suppressant to BE-86). If you want to get away from muzzle flash, consider Promo which produced smallest amount of muzzle flash compared to BE-86 and other powders.
I did a low light comparison testing for moderator taliv measuring approximate size of muzzle flashes on this thread -

"Four loads were tested using Glock 22/KKM 40-9 conversion barrel (10 rounds of each load were fired):
HP-38 4.8 gr RMR 115 gr FMJ @ 1.130" - This load was used as reference and produced 4" long by 2" high orange colored muzzle flash from the side (
Shooter's point of view - 1.5" round flash).
Promo 3.8-4.0 gr RMR 124 gr HM RN @ 1.150" - 1" long by 1" high faint orange colored muzzle flash (
Shooter's POV - 0.5" round flash). In low light, muzzle flash was almost non-detectable.
BE-86 5.2 gr RMR 124 gr HM RN @ 1.150" - 2" long by 3" high bright orange muzzle flash (
Shooter's POV - 3" round flash). This was by far the brightest muzzle flash of four powders tested.
CFE-Pistol 5.2 gr RMR 124 gr HM RN @ 1.150" - 1" long by 2" high orange colored muzzle flash (
Shooter's POV - 2" round flash)."
Medium 45ACP loads ... 4" Kimber and 200 grn bullets ... 2 powders made the cut... WST and BE-86.
If WST made the cut (which is a much faster burning powder compared to BE-86), you should consider other powders in the similar burn rate range to produce medium loads.
Here's an excerpt from my grouping of fast vs slow pistol powders around WST and BE-86 burn rate and there are a lot of powders to choose from -

Faster burning pistol powders:
Red Dot/Promo - IMR Red - Clays - 700X - Bullseye - Vectan Ba 10 - IMR Target - TiteGroup - Vectan AS - Am. Select - Solo 1000 - WST - International - Trail Boss - N320 - Vectan Ba 9.5 - No. 2 - Clean Shot/Lovex D032.03
W231/HP-38 - Zip - Sport Pistol - Green Dot - IMR Green - W244
Slower burning pistol powders:
Unique - Universal - IMR Unequal - Vectan Ba 9 - BE-86 - Power Pistol - N330 - Vectan A1 - Herco - Vectan A0 - WSF - N340 - 800X
Just seeing what you all have worked up with BE-86, and any observations you might have, for 200 and 230grn .45ACP loads.
45ACP is a low pressure cartridge and if you are looking for medium loads, essentially target loads, you will find faster burning than W231/HP-38/Sport Pistol powders are better suitable for producing lighter loads that are accurate. And if you like BE-86, consider WSF which is another "medium" burn rate pistol powders that is flexible enough to produce accurate loads at mid range load data along with full power loads.
For lighter loads, for decades W231/HP-38 has been my powder of choice to produce lighter target loads and I would suggest you definitely consider Sport Pistol which is around Titegroup to W231/HP-38 burn rate but meters better, burns cleaner and produces higher velocities than W231/HP-38. As to other faster powders, I have used Red Dot/Promo, Bullseye, WST, Titegroup with 200/230 gr bullets for 45ACP with good results.
Here's an example of fast powder in light target load still producing accuracy. MBC 200 gr SWC (12 BHN Bullseye #1) with light powder charge of 4.0 gr Promo and Sig 1911 produced below groups -

And in case you are not familiar with Promo, it is same burn rate as Red Dot but has been recently reblended to meter better and burn cleaner -
