I read one of your earlier post about your rifle before replacing the barrel. I mike my new 300WSM brass same spot you did and have .547 same as you I'm not up on the Savage rifles or their replacement barrels or any of their chambers as I much prefer having gunsmith do all the work on something like Rem/Win action
I use Wilson seater and neck die and FL sizing use a body and my body die sizes case for my chamber. After 3/4 firing I FL size. I reload for my varmint partner Tikka T-3 in 300wsm and on his fired brass I uses RCBS Small Base sizer in 300WSM and that die will size those cases to fit my chamber also and they just drop in and bolt closes real nice. that rifles never had a factory rd fired in it and fired case mikes 5.56
You might want to call Shilen and see what they say and your sized case should be around .550/.499 other choice Mikecr uses JLC might want to get # from Mike and give him a call send few fired cases fit a die to your chamber.
