I don't recall who it was but one of the writers many years ago did an experiment with this and started with a 30 in barrel and then cut of 1 inch at a time and retested, I think he went all the way down to 20in but its been so long I cant remember. You can always adjust to a faster burn rate of powder to make up for the shorter tube. Or at least in theory. There must be a valid point when manufactures stop making 26in barrels.
