If you want to be surprised shoot that 28" barrel over a long sheet of paper. Then check the amount of unburnt powder on the paper. When I shot Black powder the standard for going to maximum loads was to go till unburnt powder found on the paper and then back off.Black powder burns much slower than smokeless and barrel length was more important to velocity.
