Hi guys, I appreciate all the advice. I am very leery to have the gun modified and just wanted to see other opinions. I am hand loading the AA’s for my other 2 1/2” guns by trimming them short and using a Hartin crimp. I am not a high volume shooter, so I was thinking about buying a small jewelry bench grinder and just turning the hull by hand to grind the rim down smaller to fit the gun. Eventually, if this ammo shortage let’s up, I will buy some Cheddite hulls and RST ammo (I am down to 250 rounds of RST) and just reload those.
