like it was drill into the barrel as the last operation with a dull drill.
Made up a reamer to give a leade that removed the burr to 0.225" diameter and a gentle ramping into the rifling after that. Did not want to remove the barrel so did it that way. Then made up a lap to polish it a bit.
I think I need to try better pellets than the current Crosmans and Daisy pellets.
