    I having a 300 WSM built and currently I am planning a 24" barrel, but could be easily talked into 26". Just looking for some opinions on this matter. I already use 17, but for heavies I would be using 7828 and that is where I think the 26 would be better.

    Go with the 26" barrel. Will push those bullets a little quicker and would work better with the slow 7828 powder.

    + 1 on the 26.

    I went with a 25" barrel on my new Benchmark barrel.

    I would use as long a barrel as I could live with, depending what kind of shooting/hunting I was doing. That's to get the extra 50 fps or so with a couple more inches of tube. If velocity is not a high priority, a 24" barrel is easier to hunt with for sure. Longer barrels are also more susceptible to whip and considering a heavier contour (which would add weight) is something to think about.

    I found RL17 to produce very good velocity with 210 Bergers in my 300 WSM.

    What do you think you gained by going with the 25" barrel?

    I don't own a short-mag, but as a rule of thumb, the only rie I will own with anything less than a 26" barrel, is a .308 Win. Everything else is 26" or more.

    Just my personal rule of thumb...

    I would also go with a 10" twist, that way you can stabilize anything in the .30 caliber you might choose to shoot. But if you never plan to go heavier than a Berger 210 VLD, the 5R 11.25" twist is working awesome in my 24" .308 Win. with the Berger 210 VLD's. I can put 5 inside a dime @ 100 yards with my pet load, as long as I do my part.

    Mark is correct, contour is everything. If going longer, the heavier (thicker) the barrel, the less susceptable to barrel-whip (harmonics) it will be.

    I recommend a 26" Rem Varmint/Sendero contour barrel if you can live with the weight of it. It should make a fine LR rig.
