Is Winchester W630 still available? Perhaps with a Hodgdon designation?
The reason I ask, is this powder used to be listed for the .45 ACP in a 1911 for use with the 260gr. Speer HP. That is the bullet I used on the second bear, a 230 FMJ on the first, same load. Speer listed 11.9gr. of W630 with the 260gr. HP. That is the load I used, "give" or take 1/10th gr.
It chorno'd 960fps in my Wilson 5" bl. & shot into 2" at 50 yards off a rest. It was "lightly" tuned.
Hell of a good load.
I sold it to a fellow employee who "needed" it for her husband for his birthday.
