I have a Teludyne barrel from you, For a Savage 116 in.338 win mag.

I have one question: how much weight does that finished process hanging on my rifle weigh? How much did it increase the weight of my rifle?

Seems like a lot. 2,3 pounds?

Thank you for your time and patience.

this really has nothing todo with the barrel but in the third image from the top the rifle in the middle(the tan camo) has a muzzle brake, can anybody tell me the manufacturer or where I can find one?

Put this side by side with a fluted barrel of similar length and weight and let’s see which performs better.

Yeah. Thought so!

Why not make it an oil sleeve around the barrel to dampen harmonics and resist heating? At least that’s something you could put on a proven barrel like a Krieger…

They state the improved conductivity rather a lot, though the materials mentioned in the patents are not good conductors (calcium sulphate, cement, amorphous silica, alumina, limestone dust, clay, quartz, calcium hydroxide calcium sulpho aluminate), nor is epoxy, even carbon fibre reinforced epoxy, at half the conductivity of steel. A more useful light and stiff material would be aluminium, its conductivity is four to five times that of steel. It will be interesting to find out what they are really doing (using) to improve the stiffness and heat dissipation.

I’m thinking along the same lines as Neil above, that the epoxy around the barrel is more of an insulator than an improved heat disipator, but maybe that is the key to it. The barrel temperature may be more stable and therefore more consistant over a string of fire. This could in theort also reduce heat checking in the rifling. A further “possible” benefit is a dampening of barrel harmonics. No surprize there is an endorsement from some smallbore shooters as the pressure levels for smallbore would maximize the effect of such a system. Highpower pressures are a much bigger animal and could over power such a design.

I have two areas of interest. First the barrel life and duration of accuracy (gross number of rounds).
Second, it would seem reasonable that a thinner barrel would have substantially higher temp. so the concern is maintaining the integrity of the lans.

There is a lot of data that needs to be shared to make an informed decision. Bottom line will be the life and results when a quality shooter uses one in competition.

I’ve read their patents and the system actually works by reducing the whip effect by increasing the stiffness of the barrel. Contrary to what is stated about heating – ie improvement in heat transfer and hence cooling of the barrel – the use of the fillers stated in the patents (US20110113667 and 20110277623) would result in thermal isolation of the barrel, as the filler materials are poor conductors of heat (one is basically scale). The use of such fillers would seem more to do with the systems used on tank guns, whereby a thermal jacket is used to reduce the effect of differential heating on the barrel by winds and to keep the barrel at a stable temperature, and hence predicable barrel harmonics. Then again I might be barking up the wrong tree?
