Can someone tell me what the differences are in terms of accuracy capability between the two? The Remington 700LTR looks like an attractive rifle, given that most of the shooting I do would be at 350 yards or less. Its cool to maintain accuracy out to 800-1000, so I was wondering how much more accurate the 26 inch barrel would be?

IMO the issue between 20" and 26" is not neccesarily one of accuracy. Shorter barrels theoretically have a better accuracy potential, however for many users the practical accuracy is the same.

Generally speaking, shorter barrels are lighter and stiffer, which reduces the stress on the receiver and the amount of barrel whip.

That said, there are long barrels which shoot incredibly well.

Thre are several advantages to a longer barrel:

1- More consistent and complete propellant burn.
2- Reduction in muzzle blast and flash.
3- Lower perceived recoil, mostly due to extra weight.
4- An increase in velocity of approximately 20-25 fps per inch whe using the same ammunition. This provides a flatter trajectory and reduced wind drift at ranges past about 600 yards.

20" barrels are lighter and easier to handle.

Steve is right on with his assessment!A 26 inch gun in a bull barrel for the most part is just a little too much to be hauling
around in the field but I know some people that do.Most of the people I have dealt with in the past that build custom guns in
that fashion usually wind up building another that is shorter or having that one cut down.

Thanks guys. Like EM said, alot of guys are going to the shoter barrels. 26 inches is a bit much to carry around. My department's counter snipers use 24 inch barrels on their 700s. Some of the non LEOs I shoot with have 26 inch barrels on their 700s, but the rifles themselves a bit too heavy for my tastes.

Although I do not concur with everything the Chandlers espouse, their assertions about the greater efficacy of a .308 20” barrel for law enforcement use are right on as noted in their article in the old Tactical Shooter magazine: Chandler N & Chandler R: “Saw ‘Em Off”. Tactical Shooter. December 1999, p. 76-78. Longer barrels are an advantage at ranges beyond 600 yards or so.

One of our staff, Ronnie Frigulti, has done research and test shoots with students on this subject. What has been concluded is that no difference in accuracy has been found out to 600yds. There is a slight difference in velocity so one needs to use the proper ammunition for the particular application. Ronnie can be found at www.policetrainingconsultants.com

and who say's 6" doesn't matter... The guys at www.snipercountry.com all favor the longer barrels. It's too bad Remington doesn't offer a 24" in any of their "off the shelf" packages.

DeputyDan,

Although I agree with most of what has been posted, the first thing that needs to be discussed is - FOR WHAT? -
The accuracy differential is small, but there is noticable ballistic advantage (at long ranges) to the longer barrel. So the question stands. Are you looking for a patrol rifle? If so the chances are remote that you will need anything with a barrel longer than 20". On the other hand if you want a rifle to compete in 1000 yd matches, then the longer barrel is very useful.
Although some think the .308 is the ideal countersniper caliber, again the question is what for. I have a 16 1/2 inch Ruger 77 Compact in .308 which I consider the Ideal patrol rifle for many situations. It shoots Fed. .308 168gr match into .4" at 100 yards. For long range I have a Win. 70P in 7mm Rem. with a 26" barrel.
Different solutions for different problems.

The best,

JerryF

Jerry - good point. It would be a patrol rifle at best. I live in a very urban area, but it would also be something I would shoot for recreation. Right now, the chances of me getting to have the 700 in a car are slim. It hasnt been that long that they have let us have ARs, you know how the bosses are.

I think I will go with a 20 inch LTR when the money comes. Thank you all for the help.
