Alternatively, you can take a cleaning rod with a brush on it (one for a .44 cal) run down to the end of the bore then start it back by pulling it about 1 inch. Put a piece of masking tape on it where it exits the bore and mark the top of the tape with a line alone the bore. Continue to pull it until it makes one revolution (line is facing up again) then just measure the distance from the tape back to the end of the bore and you will have the twist rate as in 1 turn in X inches.
