As many of you may know, and get tired of hearing about.....I seem to do things backwards. I don't have a problem with what I do...it's better than sitting on the couch!
For the past several years, through my experiences, I began to settle on ten shot groups with the 44-40. I felt it better tells the story of true accuracy rather than the typical three shot groups popular today. I also settled on certain groups being about the best of the best for this cartridge at different ranges.
Recently I came across vintage 1920's information that is somewhat the same along the groups achieved at the distances used.
I came up with my consistent best which would be 4" at 25 yards with a revolver, (scoped) 3.5" at 100 yards with a rifle, 9" at 200 yards and 29 of 37 shots inside 14" at nearly 300 yards.
Seems to be fairly consistent with this 1920 information. Thought some of these other cartridges may be of interest to some of you.
