Yes they are (Short answer).
Now for my long answer. Below is "my" compilation of pistol powders by "relative" burn rate groupings -
https://www.thehighroad.org/index.p...-and-discussions.778197/page-10#post-10966508
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 - 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
No. 5 - Auto Pistol/Lovex D036-03 - True Blue - HS6 - AutoComp - Ultimate Pistol/Lovex D036-07 - CFE Pistol - Silhouette - 3N37
W231/HP-38 has been my reference powder since I started reloading and shooting matches. But I believe Hodgdon/Wichester HAD to come up with "Winclean 244" to address W231/HP-38's short comings:
- Depending on caliber/bullet weight, needed to be loaded to near max load data to make power factor
- Good for medium target loads but could not produce higher full power velocities of slower powders
- More temperature sensitive than other powders and loads that met power factor in summer would not make PF in winter
- Depending on lead lube type, leaves gummy residue in pistols
With Winclean 244 using newer manufacturing process, perhaps Hodgdon/Winchester hoped to address these issues to produce higher velocities, cleaner burning and perhaps less temperature sensitive(?) to better appeal to target/match shooters needing to meet power factor at medium powder burn rate.
But Winclean 244 has stiff competition. While Ramshot Zip is close, Alliant really did not have a powder that directly competed with W231/HP-38/Titegroup/N320 in the comparable burn rate. When Sport Pistol was released, looks like Alliant also addressed W231/HP-38's shortcomings as well while directly comparing with Titegroup and N320 enough for me to replace W231/HP-38 as my reference powder (Many match shooters consider Sport Pistol new N320 that burns cleaner) -

- Better metering than W231/HP-38
- Less temperature sensitive
- Cleaner burning
As to BE-86, I consider it modern Unique that meters better. There are many reloaders that love Unique for flexibility of caliber application but hate how it meters. During all the years I have shot USPSA, I have never met a match shooter who used Unique.
This adds to the fact that Alliant previously did not have any match shooting worthy powder in the Titegroup to W231/HP-38 other than Bullseye and Power Pistol which are faster and slower burning.
BE-86 for me has shattered all previous known accurate loads in 9mm and 40S&W (with exception of WST) to replace WSF and if I were to compete again, would be one of top powder choice I would choose, especially for higher velocity loads.
