Hi Folks,
I have about 400 pieces of .243 Brass that has been 8x shot in my 1980's Ruger 77V ( Thumb Safety) with only cast bullets ( no loads exceeding 2000 fps)
On first firing, cases were annealed and FL resized in RCBS dies. After that they were only neck sized. Now they are getting hard to chamber because the case body has expanded enough that it become difficult to chamber in this rifle because of a slightly out of center chamber.
Back in the 80's shooting jacketed at 3500 fps + I could never neck size because of this! So I adopted the practice of partial FL sizing ( sizing with the RCBS FL die until 2/3 rds of the neck was sized and that brought the body back to chamber-able tolerance! ) My concept was that the unsized 1/3 rd of the case would help center the cartridge in the chamber and the case body would fit in the out of round body of the chamber.
So my plan is to do the same with this Cast bullet shot brass....anneal the necks and partially FL resize!
My buddy however seems to disagree and said I either have to completely FL size this brass or get a Body sizing die!
Matter of opinions!....Looking for some more opinions on this!
