Many years ago when we had a major powder drought. Trying to tap my so-called friends to at least give me some to weather the storm proved fruitless. Very disappointing. (now referred to as frenemies, but I digress)
A real friend & I discovered a small cashe of Winchester ball powder called AA Plus. I have still not found any loading data for AA Plus and I have ancient reloading books.
Anyone try/use this powder? Comments?
Posted on a reloading site.
I used the AA Plus left after shotshell trials in .38 Special, on the grounds that the ammo would be shot in .357 magnum revolvers so there would be a large safety margin.
158 gr lead + 3.6 gr AA+ = 768 - 816 fps depending on bullet whether wax-lubed cast or moly coated, and gun whether 4" Colt or 5" S&W.
NOT A PUBLISHED OR PRESSURE TESTED LOAD, JUST ME AND MY CHRONOGRAPH.
Some were using BE powder load data as a guide starting 10% below starting loads and working up with a chronograph.
