That and WST burns super clean at low pressure (target loads)......
As far as Red Dot goes, not according to Alliant when I asked them. 20% isn't "virtually no nitroglycerin" content IMO.Red Dot and Unique have virtually no nitroglycerin in them as did the old ADI Australian "Clays" powders.
What is the average % for double base powders? Thanks
It varies. Red Dot is 20%, Bullseye and Power Pistol 40%, Blue Dot 15%.
There are several in the 15 to 20% range. American Select is the
lowest, Bullseye and Power Pistol are the highest.

I miss all three of the SR powders and hate when a company removes good powders from their lineup. I miss HS-5 and HS-7 too.Sigh,
all this talk about single base powders makes me miss SR7625.
I haven't tried Red or Green yet but haven't noticed any sticking with Target.Have you noticed any sticking of flakes (not due to static electricity) with IMR Red or Green?
I braved the rain for the second range test with IMR Target and decided to load the longer rounds longer at 1.155" instead of 1.150" (Sorry about wet targets. I used plastic over target papers but it was raining hard sideways). As you can see from the target pictures, shorter 1.130" rounds produced smaller shot group.For the next range test, planning to load 115/124 gr bullets with 4.2-4.3 gr of IMR Target but will be comparing different OALs to check for accuracy trends:
- 115 gr FMJ/Hardcore Match RN - 1.130" vs 1.150"

All of the Vihtavuori pistol powders are single base (No nitro content), and they burn extremely cleanly. They burn clean because of the quality of the cellulose base used
Agreed. They also said American Select was about 5%. A very good and a very clean powder.the higher the NG concentration, the more aggressively the powder attacks certain plastics.
Taking advantage of 4 days without rain, I started Vectan powder load development with Ba9.5 referencing following load data - https://www.grafs.com/uploads/technical-resource-pdf-file/20.pdfLooking forward to your Ba 9.5 load tests. If nothing else, to reduce my work, as I have plans to work a load ladder up for 9mm, minor PF in the near future.
I'm still a little surprised Hodgdon put out these new handgun powders under the IMR label. When they moved the older handgun/shotgun powders over to the Hodgdon label they said it was to bring IMR back to a real rifle powder company. It now seems it was really to make room for the new handgun power line. It does make sense.
For my semi auto testing in pistols and carbines, unless they are max case fill loads like with WST, Red Dot/Promo and Herco, they are always powder forward when the chambered rounds slam powder charge forward.I finally got around to loading some .357 with the X-Treme 158 Gr SWC and IMR Target.
One of the things I like to try with any new suitable powder to check position sensitivity ... I wonder if this newer "green" formulation has anything to do with the good numbers with the powder away from the primer?
