Triangular 700 barrels?

[P.B.Walsh]

What's up with Remington and their triangular barrels, is this really an improvement or just a showy marketing sceme? Are they better than traditional round barrels, because now they've got a 26" barreled one?

Can anyone please tell me if the triangular barreles are better than the round barrels.

Thanks

supposedly they are stronger and cool faster than the traditional round barrel... No idea whether or not that is fact or rumor.

 

[P.B.Walsh]

Ok, but are they more accuate, I would kinda assume because it'll cool off faster?

Nope. More because they would be stiffer, in theory. The stiffer the barrel, the less it vibrates as the bullet goes down the length of the tube, and the less it is thrown off. OTOH, better cooling would be helpful for long strings.

 

[PT1911]

Ditto... theory is that the thinner walls of the sides of the triangle (closest to the rifling in the barrel) would allow for optimum cooling whereas the thicker sides (the points of the triangles) would add great overall strength and rigidity to the barrel. this would "theoretically" give the benifits of both tapered and heavy barreled rifles.

warrants the question of weight comparison as one can only assume that the angled portions of the barrel would result in quite a bit of weight to allow for a barrel that is an equalateral triangle (even on all sides...)

simply put, if one were to think of it in terms of a bull barrel pulled down into a triangle, depending on the caliber, the original bull barrel would have to be quite large to result in an even triangular barrel once finished...so, though it would be lighter than the original (massive) bull barrel, it would still be quite heavy.

i think its pretty cool. a good way to shave weight. fisrt it was fluting, then spiral flutting. just giving something new. i think it worked. i also like the integral muzzle brake. there has to be a lot of stress releveing when doing that to a round barrel. unless they bore the barrel after it has been shape and stress relieved.

I did the math quik, and the surface area of a 1" circle (for the tube) is about .78 in^2. For a equalaterial triangle inscribed (all 3 points just touching the circle) it is .32 in^2. So, they could make quite a larger diameter barrel and still have the same surface area (and so the same amount of material).... So, in theory, they have something very promising.

Ok, I was just really wondering because of Sniper Central's reveiw on them, from his evaluation he got a but better accuacy off the SPS Tactical.

I am not going to hold my breath until winning target shooters and real mankilling snipers start using triangular barrels.

I don't care. Yuck. Just sign me up for a trip on the way-back machine so I can escape to an era when barrels were round, half-round or some combination of octagonal and round. Next they'll be fluting triangular barrels and arguing about whether the flat side should be on the top or on the bottom.

Gun not accurate enough? Get closer to the target.

Seriously, I'm thinking the uneven amount of metal around the bore will end up distorting the bore - even if it's bored and lapped after the exterior is profiled. Too many uneven stresses.

Not sure what the advantage is. I just bought a VTR because its something different and because of all the naysayers, few will own one. I like odd ball stuff like that.

As for accuracy, it does just as well any other stock .223 model 700.

Anyone?

No they would not be any better than a normal barrel. Its just something new to market. The only benefit would be in weight savings. I believe these are varmint contour barrels that have been planed down and they would not be as stiff as the parent barrel.

They would cool a little quicker, BUT they would also heat quicker due to less material, negating any benefit from the faster cooling.

 

[MCMXI]

It's late so assuming I didn't screw up the math, it can be shown that a triangular (equilateral) barrel having the same stiffness as a circular barrel will have 9% less weight (= less deflection) but 22% more surface area (= better cooling). Barrel's cool by convection and radiation and to a much lesser extent by conduction. The first two are improved with a larger surface area.

If someone provides the dimensions of Remington's triangular barrel I'll run it in SolidWorks to compare the deflection compared to "regular" barrel contours.

Have not been as excited, as some about the new Triangular Barrel, but the jury is still out. Will not make up my mind until true results are in, but it still don't look right.

 

[Cpt. America]

It looks cool.

I have 2. 308 and 204 ruger. first got the 308. I like it. then seen the 204 so bought that. both are more accurate then I am.

They are both 24 inch barrels with out the flash suppressor thingy.

 

[P.B.Walsh]

How did you get one without the muzzlebrake?

 

[cracked junior]

Actualy 2 with out. Cabelas has them. The only place I have seen that has them without.

Remington's website didn't have them listed until after I bought the 204 back in January. The 308 was bought in October.

I think this is just Remington bowing to pressure to make their guns incompatible with those things that go bright attached to them.

 

[Boris Barowski]

can you mount a sound moderator on those ?

anyone engineer an adapter yet ?

I would think that if you have threads, (have to turn down the barrel still) there would be no difference.

 

[MGD 45]

I'm certainly not a physicist or a gunsmith, but I imagine that Remington with it's long history or rifles, would certainly study and test this before releasing a newly designed rifle on the market. If not, they would look like fools in front of the shooting public. Of course, companies of have released stupid products before......only time will tell.

 

[jpwilly]

I see nothing wrong with them I'm sure they work well enough...why don't they just bring back the octogon? Anyway at least they won't roll off the table.
