I have several Weatherby's, including Mark V's, that I bought used. I doubt they had more than a box shot through them. They look brand new (safe queens?). Ammo is just to expensive for the average person to shoot them on a regular basis. I bought them for around 30% of retail. One is a 30-378 Accumark with the original box of ammo that I got for a song. I handload, and a buddy of mine had a break-in and they stole most of his guns (including a 30-378) so he gave me all of his brass and dies. So, there are all kinds of variables to consider. Be careful with rifles that use a gooberment caliber (.308/7.62 and 5.56) that look "tactical". They may have a lot of rounds through the barrel and some clown may have run them hot too.
