Okay, here's a question: out of the new cartridges that have been flying out, which ones do you think will survive? The Marlin rounds? The WSMs? The Ultra Mags? The SAUMs? Why will they survive?

I've heard good things about the WSM's. I think you might get a slight increase in velocity over the regular cartridge (.270 vs. .270 WSM.)
That .308 Marlin Lever Express might be the perfect cartridge if you like the way a .308 shoots and have to have a lever action...other than that specific application, it's just too much like the .308.
It'll be interesting to see what cartridges make it and which ones don't.
Just remember, just because it's new doesn't mean it's better...most companies are in business to make money.

Well, I just can't pass this subject up!! Have to give my .02 worth.
To me, the WSM's are a fad. I know they have sold hundreds and there are people out there who have done this or that with them. But wait until they have fired a few hundred rounds through the barrel. Let's see if the barrel will burn out with that hotter powder that they burn. And go by the wayside as the 264 Mag has done. I know a few that complain that their WSM won't kick out the empty cases right. Seems to have swelled to much in the chamber after firing them. Ever tried reloading one? I tried and you can do it, but the bullet can't be moved forward much because of the short fat clip. Extending the bullet hits on the front end and hangs up. Also, the ammo is a little more pricey and sure not available just everywhere.
Well, my soapbox is shakey so I'll quit. But I do feel feel better ;D

buzzard,
LOL! Good points, and astute observations. Only time will truly tell which ones pass and which ones stay. The barrel burnout (or at least throat erosion) is a possibility. But we'll see...

I could be mistaken, but its not a hotter powder in the short magnums, its the increased volume and the change in cartridge geometry that gives you the increased velocity (and subsequent pressures). They shouldnt "burn-out" much faster than the normal rounds (.270 vs .270 WSM...etc.) The velocity and pressure difference just isnt that much greater.

Schrader,
Well, I almost agree. WSM as a whole use about 10% less powder than standard rounds. They have a considerable more pressure at the barrel even with factory ammo. And have pressure spikes when reloading that make them almost unforgiving. Standard ammo have somewhat of a pressure sign curve to watch. You know what I mean, flattened primers, shiney case heads and such. WSM curve is almost non existing. They run at the extreme pressure end anyway and no room for error. As for barrel burn out!! Why would Browning and Winchester go to a high grade chrome barrel if this was not a problem? Throat erosion early on was a major factor. But I have been wrong many times and chances are real I will be again ;D I am just not a fan of any of the WSM or the WSSM for that matter. For what you gain, it's not hardly worth the effort to go from a standard round to the shorts.

Im not a fan of the WSM's - either.
However, the shorter, fatter case gives the WSM's MORE case capacity vs the original...look at Hodgdon's Manual. Because of that, they do have a higher pressure and higher pressure curve.
