I have a question, folks:
With a 5.5" Ruger Bisley in .45 Colt, I more or less know what velocities I can get with various bullets using 2400, N110, H110, or Lil'Gun.
I also know that a small amount of data exists for Ruger-only loads using faster (I'll call them 'medium fast') powders, such as Blue Dot and 800-x.
Nosler shows 800-x data for a jacketed 250 grain bullet, that if extrapolated to a cast bullet in a 5.5" revolver, would show 800-x giving decently high velocity - halfway or maybe 2/3 of the way up from 14k PSI loads towards the top speeds obtainable with the slower powders in Ruger-only loads. I've extrapolated this data to load a few rounds with stiff charges of 800-x but haven't chronographed them yet.
John Linebaugh has shared load data using HS-6 that very nearly does what I want to do with a revolver.
Hodgdon has Ruger-only .45 Colt data for Longshot powder that very nearly gets me where I want to be.
Here's the deal: I want to end up with a 270-grain bullet, more or less, running between 1150 and 1300' MV. I realize that I can go past this with the slow powders, and pass it by a great deal. In light of that, in theory, if I can reach my target speed with a faster-burning powder, I might be able to do so with a lighter charge that would be both cheaper and easier on recoil.
So.....in that broad gap between 800-x and H110, what's out there that people have used in the past with good results in hotter .45 Colt loads? It seems as if HS-6, longshot, and 800-x will all reach the low end (1150') of the range I'm looking for.
What else might I try?
