Just a guess, but I would think about -30 fps per inch.
I think a 22" would be pretty good.

JD is right. A 22" barrel would likely balance better, and the weight difference on a sporter barrel that has lost two inches is minimal.

I agree with JD and DrMike, 22" would be just about right.
As far as powders go I only use RL 15 in mine but that is because I'm getting 2850 fps with 56.5 grains and 200 grain Hornady SP and if I'm doing my part 3 shots touching. Most of the time I hover just under 1.5". I didn't work up the load, the guy who sold me the rifle had worked it up. I never messed with his formula after I saw how good it could shoot.

my wife' 260 rem. with a 20" barrel shoots rem.factory 140 core lokt loads at 2550 fps as compared to published 2750 fps.
but i dont know if that tells anything.

Everyone that mentioned going to 22 inches is right on in my book. My Sako is a 22 inch that has been rebarreled from a 7X64. The load used is R15 and the 210 Partition at 2745. Groups nice cloverleafs all day. I don't use it for elk, but it is great medicine for moose. Make sure whoever cuts it down knows how to re-crown it properly.
When I had my 338-06 built I elected to go with a 24" barrel. The idea was that if it turned out to be too ungainly then it would be a simple matter to cut down.
Several years later it is still at 24 inches.
I had mine cut with a long Weatherby type throat and with 225 grain bullets I can get 2750 fps with a 225 grain Hornady SP
laker, my 338-06 works well with IMR 4350, Hodgdon 4350 and Winchester 760.

I like my 24" barrel on my Sako m75 Greywolf 338-06AI. Cant give you velocity as no Chrony but from being new it shoots 225gr Accubonds superbly. Now to get the AI reloads made and get to the range :grin:
For a lightweight I wouldt go less than th 22" menioned already. Maybe get like a #3 or #4 barrel and flute it.

.............I don`t own a 338/06, but I do own a short 16.5" barreled 300 WSM.laker":hg7lygi5 said:
In comparisons to two 24" 300 WSM`s using the same identical loadings, the chronographed results on the average were from 4.2% to 4.5% in overall velocity loss. That was from a barrel 7.5" or 31% shorter than a 24" er. In my experiments, the loadings averaged a loss from 15 fps to 21 fps per inch of shorter barrel length.
Since your talking about only a 4" difference, you`ll probably be around a 3% difference. For a 22" barrel even less.
Whether you use a 20", a 22" or a 24" barreled 338/06, your results will be the same on whatever game you`ll hunt given the same killing distances.
