Having a Weatherby rifle for more than 40 years, I finally bought a .300 Wby Vanguard in 2009. I liked it so much that a few years later I bought two more Vanguards, one in .223 and the other in .308 Win.
The last two are my weekly practice rifles, for shooting the 200, 300, and 400 yard steel gongs at our local range. Depending on the wind, I have developed handloads for each of my Vanguards that will shoot 3-shot moa at each of those ranges.
As for buying used rifles, both of my 7mm RM rifles I found in pawn shops, and again I have developed moa handloads for them, and I have used each of them on multiple international hunts.
