I have a Vanguard S2 in .308 that shoots great, but I too am considering some modifications. Specifically, I plan on having a gunsmith shorten the barrel from 24' to 20' or 21' and put an 11 deg crown on the muzzle. This is because I hunt mainly from a stand in dense woods and it would help to have a handier rifle. I am also considering ordering a laminated stock from Boyd's or Stockys, which I would probably modify to free float the barrel. Please report on how your free-floating project works.
