300 WM with 20" need advise...

I have everything for my build at fine Smith ( and best friend ) ready to go together. I recently heard a descusion on barrels and was thinking of giving a 20" a try in this caliber. Being new to reloading I was wondering what powder would be best with a shorter barrel in the 300WM ? I was watching a video from Accuracy First / Magpul and the instructor ( Todd H. ) is a big fan of heavier / shorter barrels ( 20" ) and a faster twist rate for long range shooting. I know there is some loss of FPS and that is mentioned in the vid. as well. I would like to have some input from the shooters at large on this. Thank's for your time.............Rick

20 inch barrel just doesn't make sense to me in a 300 win mag. Would be a much better fit for a .308. With a 20 inch barrel in 300 win mag you are simply getting 30-06 performance.

+1 30-06 performance with more expense, recoil and muzzle blast. less magazine capacity. All the negatives of a magnum without any of the benefits, I wouldn't do it but at the same time I am sure someone has, so you would not be the first to do something that just didn't make sense to me, she is your rifle I hope you enjoy it either way....good luck

P.S. I have heard of some benchrest guys and pistol shooters putting magnums in short barrels but even if it reduces whip in the barrel it seams more novelty than practical application...................Disclaimer: All this is coming from a guy with a 24" 338 edge (which I love) so judge my opinion accordingly.

Not quite on the '06 performance in a 20" barrel. My father has one of the savage stryker pistols with a 14" barrel in 300 wsm and it will turn in average '06 sporter velocities.
If you want to do this you will loose some speed, and you will land midway between the '06 and 300 win in actual velocity. I've been working with contenders and strykers for years, and 400 fps loss to go the pistol barrel is about it.
The trick is to find a powder whose energy is expended by the time it gets to 20". Use the fastest powders that produce full velocity in your cartridge. rl17, 4350(both h and imr), 760, etc. for mid weight bullets in the 300win. If you step up to 180, I'd go to 4831 class, but no slower than rl22.
If I were a betting man, I'd say you can still net 3200 fps with a 150 and 2900 fps with a 180.

P.S., the short barrel absolutely helps accuracy. My stryker pistol (22-250) will pitch 5 shots into an inch at 100 yards with one sandbag under the heel on the pistol(4x leopold on top), and I've killed prarie dogs at 1/4 mile with one of my father's strykers.

I know conventional wisdom says the shorter barrel will have less whip and a short action is more rigid but I have a long barreled, long action that can do .25" @100 so you have to ask how much it really matters.

It's more a fact that anything you put through the short barrel shoots better. I've got 26" barreled la sporters and they shoot well. I've seen pistols with 14" barrels turn in 5 shot .25"-.5" 100 yd groups with a 4x scope, and I've done it a bunch of times myself. If you don't have to worry nearly as much about harmonics, you can get the gun going quickly and get used to your load, instead of playing the load hunt game.
By the way, the 300wsm pistol I refered to has a 14" barrel including the muzzle brake.
It's what the OP wants, and it might just be a tack-driver.
