I have been looking at a nice C.S. Rosson 20 gauge for some time now, but I refuse to buy it because it needs 2 1/2 " shells. I see absolutely no place that has them for sale. So, am I going to have to take the gun to a gunsmith to check the chambers and lengthen them if he can? Is that my only option? I would hate to buy the gun and then find out the chambers can't be lengthened. I have a 20 gauge reloader that I reload 2 3/4 " shells, but I don't see any way to get my MEC to make 2 1/2 " loads. That plus I have no empty hulls. What do you gentlemen do when you need 2 1/2 "-- 20 gauge reloads? Thanks for any opinions.
