Barrel Length ?

For a .300 win mag, do you get anything ( performance wise ) out of a longer barrel ? The barrel lengths I'm comparing are the 24" and 26". Does it increase accuracy or bullet energy at all ?

Usually a couple of inches

Usually a couple of inches more in barrel length will give you a some extra velocity along with more energy at the muzzle. But the difference between a 24" and a 26" barrel shouldn't be that much and if you get the longer barrel you will notice it if you are packing it around in thick timber or brush. Now necessarily in weight but in the extra 2" hanging up on things.

Biggest difference oir most

Biggest difference oir most important difference between 24" and 26" will be the way the rifle handles. You will get maybe 70 to 100 FPS more velocity.

It is true about longer

It is true about longer barrel faster bullet speed, But if you relaod you can get that extra speed if it is that importan to you,

you can read all the books and blogs, you will get a 50/50 split

IMHO 24 inch barrel will serve you fine

So if it's true that you get more velocity from a longer barrel, and you reloaded to get 26" velocity out of a 24" barrel, wouldn't that in turn give you more velocity out of a 26" barrel?

I do agree that a shorter barrel is easier to manuver if you're hunting in thick brush which would give a slight edge to a 24" vs a 26" barrel. However, if you're more into 500 yd plus shooting, the extra velocity is your friend so you might want the 26" tube.

The barrel on my .375 RUM with it's KDF muzzle brake is 28". My .300 Weatherby with it's KDF brake is 26". I've never taken a shot beyond 350 yds at a big game animal with either of these rifles, nor have I ever felt hindered with the barrel length of either of these rifles when I was hunting in the brush.

To a point and then there will be negligible to no difference between the two, as sooner or later you will max out the efficiency of the longer barrel. A chronograph should tell you when that occurs.

If it matters to you, then go big

I use rifles with the following barrel lengths right now (have had lots of others come and go):  28" (.264), 26"(7mm RM), 25" (8mm-06AI), 24"(7mm WSM).   I've used the long barreled .264 more than anything else and I don't find the length objectionable in the woods, and in fact kind of like how longer barreled rifles handle.  It's a little more like a shotgun to me.  But, I also handload and like speed, so I'm willing to accept a little extra weight and length for a little extra speed.  You may not be like me though.   Now with that being said, I think your action is just as important and if comparing two different actions, there will probably be a lot more reason to justify a preference in my mind than 2" of barrel length.

I really never did worry too

I really never did worry too much about barrel length on a rifle but I did notice a big difference when I started hunting with a single shot rifle such as the Ruger #1. Once you get rid of the action you have lost around 6" overall and will notice it when in heavy timber or brush.

I would not doubt that. But the ability to load a 24" load to the same velocity as 26" barrels is touchy. Problem being that at some point, the shorter barrel will have to exceed safe pressure level's to get the same velocity's. Also the gain per grain of powder start's falling off over max. The long barrel does provide a velocity edge you probably cannot equal with a 24" barrel. Some people don't find the handling uality's of the longer barrel anything to worry about. But then I suspect either they don't hunt heavier cover or haven't got much time behind a shorter barrel.

My favorite hunting rifle ever had a 20" barrel. granted I did not get the velocity of the longer barrel's but it was still plenty of velocity for any range I'd likely shoot, got a 300 yd max on myself. O have now another rifle with an 18" barrel, at some point I'll change out to the 20" again, both rifles are the same cartridge. I will not be at much disadvantage to longer barrel rifles. The 18" just seem's awkward to me. I also have now a Win mod 70 featherweight, newer one, with a 22" barrel and I really like it. Probably the best length for me over all is the 20" or 22" depending on cartridge. 

My 25-06 has a 24" barrel and it's been really nice to carry and handle. But if you wanted a bit more velocity there are better ways to do it than getting a longer barrel. Get a cartridge with larger case capacity!

Very true!  You can't argue with the laws of physics.
