Case gages are very useful.I bought another 30/221 reamer from PTG.The Clymer reamer is based on the 1.4" OAL case.The PTG is based on the 1.35" OAL case.Longer case won't work in the shorter chamber.Most first time brass forming is from once fired brass.Mil brass is thicker and tougher.The problem is usually the shoulder neck area.The case has a very short shoulder but the forming leaves a radius here.It hits and causes problems.Once fired its good.The Redding dies need a good bottoming out to work on a Dillon press.So If the round drops into the gage it will work. Mil brass had neck separation after 5 reloadings for me.I would anneal the neck area after cutting to 1.4".This is a lot of work.One guy bought a barrel from me and had Teppo Jutsu build the upper.It wouldn't fire the ammo he bought from someone else.He was unhappy.Trash the upper after much $ or trash the ammo.Don't know how it turned out.
