Re: 7 stw vs 7 ultra mag

A few years back I knew about a half dozen guys that ran a reamer thru Remington barrels to build a 7STW. Of those guys only one still shoots the round. And he's well into his third barrel! The poster is correct about the ultramag eating barrels as it's even more overbore than the 7STW! The cartidge choice for me would be the 7mm WBY mag without a second thought! Better neck and shoulders than either of the others; meaning much better barrel life with simililar velocity. But on the otherhand there's still nothing wrong with the generic 7mm Remington mag, but given the choice it'd be the Weatherby everytime.

    So how many rounds do you think you can get from the 3- STW,ULTRA MAG AND THE WEATHERBY all 7mm without overheating them. 2 shots then cool before firing another one
    Thanks Guys

    Depends on the thickness of the bbl. Lay your hand in it, don't let it get hot.

    It's not so much the barrel itself, as the chamber design. I doubt that the Krieger would last anylonger than anybody elses barrel being as 90% are cut from the same numbered steel. Just can't take that kind of heat.

    Also ambient temp, barrel flutes, moly bullets, finish of the bore. Feel the barrel, when it gets warm, give it a rest. This is why I don't like timed fire, 20 rounds, one after another. Really hard on the barrel.

    Call me prejudice, or call me, been there, done that. But that is a hands down 7MM STW answer. The law of deminishing returns comes into play here also. The velocity difference between the two, versus the powder to get that is quite high. That being said, the more powder you burn, so does the barrel. I have been a STW fan since it's conception, and have experienced extremely long barrel life in my own rifles . ( plural)
    I have heard of 1200-1500 rounds before burn out. In the case of the 7 RUM, I have heard of them " biting the dust" at way less then a thousand. Actually heard of one that didn't see 600.
    As another part of your equation, I would like to throw in the accuracy and shoot ability issues. I had a 7 RUM a while ago, that at best was very finicky. By the time that I got the thing to shoot, I had about 200 rounds through it. Hear comes the good part. When I finally did get it to shoot, the velocity was no better then my STW's. And to be totally honest, it wasn't as accurate as all the hype made it out to be. I believe that you can have TOO much of a hood thing. What I mean by that is, the 7 stw is about as overbore that 7mm can be and still be SHOOTABLE.
    This may give you a little to think about. But my vote goes to the STW, imagine that !!
