Wanting a long range toy!

At some point, it's just friction. You don't need a 26" barrel, then add a 7-9" suppressor to the mix. There is some amazing stuff being done these days with 18" barrels of nice quality and good muzzle work.

This is the one I was looking at:

Lots of guys are shooting 308s at 1,000 and doing very well. The F-Class (TR) guys must use 308 or 223. Almost all of them are using 30-32 inch barrels. Trying to burn as much of the powder inside the barrel as possible.

Long barrels with a can on the end isn't a big deal. We aren't jumping in and out of vehicles with them or kicking in doors.

Shorter barrels equal lower velocity. But they do look cool.

The current fascination with short barrels I just don't get .

With a shorter barrel you have to push the cartridge harder to get the velocity which translates to shorter barrel life .

Long range precision rifle is about ballistic advantage . The two biggest factors in that are velocity and the bullets BC . Shorter barrels sacrifice velocity which translates to more drop , not a huge problem , and bigger wind holds , a large problem .

If you need a stubby gun for the conditions , vehicles , MOUT operations , etc. in my opinion your better served with a gas gun .

This also depends on your definition of " long range " . Out to 500 you can get away with a lot that past that makes a big difference .

But SH Frank said I don't need a long barrel...

Listen to Chuck & Hoser, they know what is what when it comes to LR shooting.

[C Ward]

Frank doesn't pay for barrels or gunsmithing .

Don't get me wrong Frank's a damn good shot and definitely knows what he's talking about .

But the typical matches around here you get one shot and thats it . So I'm all about maximizing danger space and minimizing wind holds as much as possible , which gives a bigger error budget .

Thanks. I will look for a 24 or 26.

Starting looking around, is there a fancy chart that shows bullet weight, barrel length, and barrel twists that would be optimal? I've see the one for AR's 55gr vs 62gr

24" barrel - 1-10 twist
26" barrel - 1-12 twist.

[Zombie Steve]

Just my opinion... for .308 just get a 1:10 twist and be done with it.

[C Ward]

Either one should work with the 175 or 155 grain bullets . The 1-12 is close to the edge and 1-10 is over stabilized. Up here at altitude you can get away with less twist because of air density .

The Palma shooters are running 1-14 with the 155's . My 308 is 1-11.25 . There is a school of thought that you never want to spin a bullet any faster than you have to , Walt Berger is a huge proponent of this . I can't say that I've ever seen any ill effects from over stabilizing first hand .
