The only issue WAS factory loads of proper shot chrge and pressure, reload data for proper loads, and the reasonably available/widespread knowledge as to what was proper for 2 1/2" chambers. These things are now solved. If a potential buyer balks at the 2 1/2" chambers, he/she is ignorant and you need to educate or is trying to gouge you. There are plenty of buyers out there now who have been educated.
