I already elaborated. One guy being able to shoot a rifle 1/2 MOA and another guy being less comfortable and only getting 1 1/2 MOA is not the fault of the rifle nor the barrel length / contour.

Higher velocity, and higher BC do help at longer ranges. We have not talked about long range, just the consistency of the rifle/ ammo.

Ever rifle barrel and every bullet create a sine wave. You cannot overcome it with a different bullet. You can lessen it by making the barrel
a. Thicker
b. Shorter
c. Both

How can you not see that it is the fault of the rifle? Hand a tack driver to a great shooter and he will drive tacks. Hand a tack driver to a chit shooter and he will spread them all over the paper.

I have two 20 inch barreled .308's... one I bought with the plan to rebarrel longer but it shoots so good that now the plan is to try and wear it out.

Tac Ops specializes in 308s using Remingtion action. Guaranteed 1/4 MOA using Factory Match ammo I believe. Your search just ended unless you have other considerations such as budget in the way, lol.

What's the most accurate 308 rifle for deer hunting at moderate ranges, say 100 to 400 yards? I'm speaking more in terms of barrel weight than rifle brand. Normally I like Ruger, Winchester, and Remington, so brand is not that big of a deal. Also, I'm not talking about AR's. You guys that love AR's more power to you but I'm a bolt action guy.

Barrel length and barrel contour have nothing to do with accuracy. The quality of the rifling, the chambering, and the quality of the ammo determine accuracy.

The shorter the barrel the stiffer the barrel. Which means the short barrel tends to be less picky about the powder charge you feed it, or the mass produced ammo you feed it. Provided you are using quality ammo. The short barrel produces less muzzle velocity.

The long barrel has a more pronounced sine wave and can be more picky on powder charge, making "the node" a narrower margin. The longer barrel produces more muzzle velocity. A thin long barrel heats up after less shots than the long thick barrel. Once the long thin barrel heats to the point of stringing then it can shoot very erratically. The purpose of the long heavy contour barrel competition shooters use is to get more muzzle velocity and also have enough steel around the bore that it will still shoot consistently after extended shot strings.

For hunting, the barrel length and thickness is up to you. If you want a light, handy two or three shot rifle the middle ground I like is a 20" sporter contour. You maintain velocity and do not have a super heavy barrel to tote around. You can also go down to 16" at the expense of velocity. The general rule of thumb is 20 fps MV loss per inch of barrel taken off. If you find a sporter contour rifle you like you can always have it cut down as short as you like down to 16" without an ATF NFA tax stamp.

24" Remington 700 5R Milspec. Superb accuracy.
