I never cared much for Weatherby rifles, and frankly do not know much about them. I hunt with a guy who has two of them, and has had more than his share of problems with one; the other is a 300 yd tack driver. So, on an impulse without doing any home work, I bought one. I bought a Mark V in 30-378 and put a vortex viper scope on it after an exhaustive search for rings and mounts that would stand up to the recoil of the gun. (I ended up having to call the Blackhawk people and get them to describe to me exactly what I needed.) I started out with Leupold single screw rings, and knew I had a problem after the third shot and the scope was gone. It was lying on the grass behind me, undamaged. Fortunately I am used to being laughed at when I go to the range. I think people instinctively know when I am coming and they buy tickets to see what I am going to bring and what stupid move I am going to try next...like when I tried to drive a 50 grain NBT through my 22-243 at 5000 ft. per second. Well, I read an article that said it could be done! My old shooting glasses now hang in my gun room with bits of steel still imbedded in the right lens. Anyway, back to the Weatherby and more of my ignorance. I was perusing the Weatherby website to see what was available, and they mentioned a Mark V, and a Mark V Accumark. When you click on each, you get a picture of the same gun with a $500 difference in price. The only difference I could find is that a Mark V has a six lug bolt and the Accumark has a nine lug bolt. But then on a different spot on the site, it explained that only the magnums have the nine lug bolt. All Mark V's show a factory brake, which mine has. To confuse things even more, I paid $900 less for my rifle than anything listed on the Weatherby site. So finally we get to my question: are all Mark V rifles Accumarks, or are there two different Mark V rifles? And how did I get a rifle with an MSRP of $2100 or $2300, depending on where you look, for $1200, NIB from the most reputable of all dealers on the planet? Thanks.
