Yeah, weight vs. accuracy trade off at that extreme.Or they use it to inflate the pricing to the government?
Go to a big shoot and look at the top 15 shooters rifles.
How many are fluted? Believe me if it helped they would be!
Actually if we could check it the barrel changes every time it's shot
It relieves stresses through vibration and heat.
I have read about those structured barrels you make. Can you make one that will fit in a desert tech HTI?Focusing on a 50bmg platform (and applicable to varying degrees to smaller calibers).
Fluting removes weight. Obviously the deeper the flute and quantity reduce more weight but at the decrease in strength of the barrel ie... increased harmonics.
Cooling area does increase but on shallow flutes minimally as you are removing a cord of blank length and replacing it with a cord of slightly longer length (CAD a barrel).
Wrapped barrels: the strands go the wrong way in order to dissipate heat. They retain heat (this has been noted in earlier posts to great detail).
Obviously the end user has to place the three main categories in their preferred order of importance: harmonics, heat or weight.
Please look at our barrels on TACOMHQ. Our barrels have been extensively modeled in high end computer simulations and field results absolutely back them up including 3rd party results. We can calculate the barrel well within a half a pound typically for those making a weight class.
For the 50 application a 1.8" diameter barrel will weigh 13-19lbs based on lengths of 30-40" long. A 32" 1.5" diameter barrel is 6-7lbs. Its cooling area will be 300+% greater than a solid barrel as they are truly radiators. They will be 50+% stiffer for the same weight. They will have a longer barrel life. They will typically be much more forgiving during load workups. Testimonies do exist including from Cal's- Let's just say he was nearly dumbfounded when he shot our barrels and is ordering one (see his video). Members from AB, JJRock, GPG, Cutting Edge .. are all testing our barrels. Videos from 3rd parties attest to all of the noted claims.
We use all of the major blank producers including K&P. We take a great barrel and improve its base attributes.
We are entering several DT projects (ELR) so this is (or could be) good timing.
How confident do we feel about our barrels? If they don't shoot as good as your comparable barrel we will buy it back.
