Okay, gunslingers, gnat-knockers, brass-packers....I've seen lots of targets on here, heard lots of data, but I haven't heard your opinion on what you think is the most accurate round out of a "carbine" or short barrel. Chime in.

hmmm let me think about this.....I dont have a clue. I dont know why a shorter barrel would change anything as far as which calibers. Most often it is not the caliber that defines accuracy, it is the weapon and how it is made.

All rifles will be more accurate with a shorter barrel over a longer barrel (all other things being equal).

That being said, what you are looking for is a caliber which is capable of using case capacity (ie burning the powder) in a short barrel.

All the .308 family (.243, .260, 7-08, .308) are quite accurate and are still quite efficient even with a 20" barrel.

Why would you think a rifle would be more accurate with a shorter barrel?????

I realize that my response does not address the specific question asked by Goat-roper, but they are more "efficient" in a 22", 24" or most of all a 26" barrel. For every inch that you chop off from 26", you lose quite a few fps(velocity), which in turn gets back to the efficiency of a round, doesn't it?

you are correct 4onaside. If you really want a long range rifle your talking around a 30 inch barrel.

I realize that anything beyond 26" inches becomes impractical from a handling standpoint(although I once owned a model 95 chilean mauser that had a 29" barrel, which I cut off to a more practical length). Most all of your ballistics tables use 26" barrels to arrive at their figures. I own two 26"rs, one of which I just bought for my next year's(hopefully, LOL) prarie goat hunt. However, at the ranges that most of us shoot for whitetails all of this is really immaterial, 18, 20, 26, or whatever.

Steven,

shorter barrels are more inherently accurate because they are stiffer. Same reason a #8 contour is more accurate than a #2 contour. Less barrel vibration as the bullet travels through the bore.

Again, this is all other variables being equal.

he is talking accuracy in carbine lenght barrels dudes, not rifle lenght barrels it has to do with barrel harmonics and short stiff and thick is what he is thinking i think... now lets put it into perspective in rifle lenght barrels say you got a remington 700 sendaro in 7mm mag with basically a heavy sporter tapered barrel and then you take that gun and mount a remington bull barrel on it in the same caliber and lenght that bull barrel will more than likely be more accurate its is the same principle with carbine barrels also you can have the narrow taper carbine barrels or the thick and stiff type which more more than likely be more accurate over the course of your firing due to differences in barrle harmonics and vibration, a stiff barrel is just more repeatable over the long run hit wise from round to round. that is on equal footing with everything in the setup with a sporter tapered barrel in the same lenght and caliber for the vast majority of times..
