I checked, it was Dixie Gun Works. 40 caliber, patched round ball, 47 grains FFFg black powder. Started with 40-inch barrel, and kept chopping it down until it was 20-inches. Fastest velocity was the longest length. Lost velocity each time it was cut. So the barrel was not long enough at 40-inches to reach that point of equal pressure for friction to take over and slow down the patched ball.
been tested here with a chrony,they are wrong. we've done it with a tc triumph,tc omega and a knight. they all gained fps.simple test .i just bought a 45 caliber cva inline that i may shorten today. we have gotten better accuratcy out of all of them with 20-21" barrels. doing away with QLA on a tc gun may be why mine is more accurate.
