I have a couple "Improved" chambered Handi-Rifles, a 280 Improved-improved, and a 35 Whelen Improved-improved as Wayne York calls them who did the rechambers, factory ammo can't be used in them due to way too much head space, I just neck the brass up, 280 Rem to .308" and Whelen to .375", then form a false shoulder to head space on, then fire form, works great. I also have a 30-30AI that I reamed myself, rimmed chamberings requires no special treatment, will fire factory ammo just fine, but don't be surprised if you get some split necks even with factory ammo, and make sure you don't push the shoulder back too far when resizing, it still should head space on the shoulder to save the brass.
