Remington 700 VS Composite Barrel Rifle .308
- Thread starter JJ-65
- Start date
Thin barrel with a composite wrap, allows varmint size barrels with slightly heavier then sported size weight. I doubt there is any difference in erosion or bbl life. - dan
Actually, US army trials found carbon wrapped barrel accuracy exceeded requirements well past 5 thousand rounds, whereas all steel barrels were finished by 3 thousand rounds. Only the ten to one cost ratio kept top army brass from adopting the the C/W barrel.
Interesting, I did not know that - dan
I guess you answered your own question.
Depending on the thermal conductivity of the carbon fiber used, it could actually make for a barrel that gets hotter internally, similar to wrapping insulation around it. Which is usually not good for barrel life.
So was this analysis you mention based on proper bore scope analysis and comparison over many barrels of each kind? or " it just happened to shoot well longer ", which could stem from other factors.
To me there is nothing about it that would logically or magically make it reduce throat wear, it would be about equal to giving a car a coat of paint and expecting another 100,000miles out of the engine.
The 2 together might make for better harmonics that could improve accuracy. I would expect this is where much of it is, and some possible placebo effect.
I'd be quite interested to see how the steel and carbon fiber behave together over consecutive firing as the temp rises and stresses change, as I do love experimentation, but it needs real data.

With the general lack of experience around here with anything but the most common of guns, one must be able to do his own research.
Or at least be able to read, lol. - dan
