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.

4 3/4 Bbl Pietta:

1. 925
2. 903
3. 927
4. 923
5.934
Average 922.4

Cimarron 5 1/2 Bbl :

1. 1004
2. 967
3. 1048
4. 1070
5. 1047
Average 1027.2

Uberti 7 1/2 Bbl:

1. 1028
2. 1049
3. 1018
4. 1026
5. 1010

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!
