Can't argue with the Mark V comments and don't know much about the Vanguard series, but my very first large caliber rifle was a .300 Weatherby that I got in 1963. My dad picked it up somewhere in a "deal" and gave it to me for my birthday. It was built on a hand-lapped Mauser action, probably a '98 but I didn't know the difference then, and it was a tack driver. It was also the most beautiful rifle I ever owned. It was factory production, Weatherby scope and all, so that must have been one he made before he started making his own actions. There was a 200 yrd range where we lived (it was the only one I knew of longer than 100 yrds back then) and that rifle would shoot 1.5" groups at 200 yrds. with factory ammo all day long. Being young, I left it as collateral for a motorcycle I bought three years later and by the time I had saved up the $500 for the motorcycle the guy I left it with had sold it without even contacting me. I still miss that rifle 50 years later.
