Thinking about picking up pawn shop gun and converting to 7MM STW.
1) Would a standard 110 chambered for -06/270 size cases work? Just change bolt face?
2) What needs to be done to magazine, going from .473 to .532 size cases and longer case of the STW?
3) Would it be better to start with a 7MM Rem gun to convert? (prolly a no-brainer question)

Any guidance will be appreciated.
