I am still very new to centerfire rifles and I'm trying to learn as much as I can. I recently bought a model 16 in 7mmWSM. I'm on the list at SSS to get T&T'd. I think I'm going with a McRee Precision stock. The last decision I have to make is what barrel and what cartridge. I am definately favoring the 7mm RSAUM but I'm trying to figure out chambering. More specifically when do you need a custom reamer?
If I order a barrel chambered in 7mm RSAUM what am I getting? I know you need a specific reamer for chambering in 7mmWSM when you are planning to use 300WSM brass. Does this mean you can't ever shoot factory 7mmWSM rounds? One of the guys over at Benchrest forums used a PT&G reamer designed specifically for 7mmRSAUM based on resizing 300RSAUM brass (Nosler specifically).
Is it simply not possible to setup a chamber that can shoot factory 7mmRSAUM as well as reloads with 180 Berger's based on either remington brass or Nosler/Norma 300 RSAUM brass?
If I know the majority of my rounds will be reloads should I consider what my "usual" load will be based on and pursue a reamer that fits that combination?
Thanks for the help!!
