I also posted this in the Dark Arts forum.
Hello everybody!! I was finally able to get out in nice weather to chrono some BP 45 Colt loads out of some SAA clones.
The guns used are a Pietta (Heritage Big Bore) 4 3/4in, Cimarron Old Model P 5 1/2in, and a Uberti Old Model P 7 1/2in.
The load is 40 grns of FFFG (3F) Olde Eynsford under a 250grn PRS Big Lube bullet. All loads fired 10 feet from chrono.

For BP loads you may want to get your Chrono a little farther out as the smoke will give you readings that are not accurate. wM1

Pretty well checks with what "Duke" Venturino recorded.

I have always found that using FFg makes recoil more manageable as well as gives better accuracy in a revolver. YMMV.

Thank you for the info. It will be useful for comparing with other loads. I use Swiss powder , I wonder if it has the same or close burning rate as yours.
how could you load 40 grains? tight compression? I cant load more than 35 grains in my cases with my weak single station press.

I use the 2.5cc Lee dipper which shows 40 grains in 2 separate BP measures. It is a heavy compression!
