The .44-77 1980's made Farmingdale Shiloh

[Don McDowell]

Kurt, with having the ability to test loads from set the target on fire to 1000 yard plus. I can guarantee you that going past 1.3 inches long in the 19 twist 44-77 will give you nothing but grief the closer you get to 800.
I also found that a small bullet and heavy paper to be extremely detrimental to accuracy. Thinner paper and a bullet no more than around .004 under bore diameter eliminates 99% of the unexplained dirt diggers.
