I'm a long term user of 231/HP-38, Unique, BE, Red Dot, etc. I have an opportunity to buy an 8lb jug of Alliant BE-86.
Data is scarce for this new product but it seems to have a wide range of caliber usage from .380 to 44mag. according to the Alliant website.
Any pro or con info from personal experience would be appreciated.
Thanks!
