I have been playing around with some brass trying to "season" it. Basically just trying to shoot a couple of low pressure shots through some new brass hoping to work harden the case heads without expanding them, with plans to anneal the necks and then fire full pressure loads. Anybody else played around with this? I have a couple of really tight chambers, very close to the unfired case diameter. I tried small base body dies with little sucess. I find that when I fire full pressure loads without "seasoning" the brass I get the dreaded click. Anybody useing this work around for overly tight chambers? How well is it working for you?
