Checking in to see if Structured barrels have started taking over any discipline in shooting......
Crickets*
... OK will check back in a few years.
We just ran two surveys:
1) Does barrel stiffness matter? Over 600 replies. 96% YES 4% NO.
2) Does barrel heat matter? Over 700 replies. 98% YES 2% NO.
I am sure you you are in the NO votes for both surveys.
I am sure you know what the Second Moment of Area is: Definition. The second moment of area is also known as the
moment of inertia of a shape. The second moment of area is a measure of the 'efficiency' of a cross-sectional shape to resist bending caused by loading. Both beams have the same area and even the same shape.
Concerning Heat Transfer:
The rate of heat transfer is directly proportional to an object's surface area. This means that a larger surface area will result in faster heat transfer. For example, a larger metal plate will transfer heat faster than a smaller metal plate. This is because a larger area has more surface particles that can conduct heat.
Please provide your counter math to explain why our barrel falls outside of this basic principle. We have had multiple engineers and computer simulations that note our design is superior to a standard tube.
Please provide your premises on why our increased surface area does NOT effect long shot strings.
You posted your 6mm group. To note our group shots 45-50 were superior to your posted group. Minor fact. However, it was an opening for you to show your 50rd group- please provide it. Take NOTE: if you even come close to our group I will jump to 75rds, then 100rds... get the picture. Your barrel will get hot, it will shift POI and the groups will open up... Are you really going to deny that? I will say "YES" as I am sure you voted NO on both surveys.
I understand that this performance has no bearing on F1, Bench or PRS. It is a technology THAT WAS NEVER meant to compete in those venues. Throw away barrels that never go past 20shot strings is not our cup of tea. It is a technology to reach higher velocities with longer lives and reduced extended group size.
But we also posted extended groups for 300Norma and .416Barretts....And you will instantly say that nobody does that. We have a MRAD300Norma on a base. It has nearly 2krds through it. "I dumped 3mags as fast as we could- we had to put our notebooks over the barrel it was so hot- swung to a 100yd target and shot a sub MOA group on target/aim point". Now who would possibly care about that performance?
We have a .308 in mil comps: one of the stations recently shot was an unlimited round count for hits in a given time. One of the competitors barrels was "dripping" when the station ended. Dripping barrel= bad "fire fight" in my opinion. The dripping barrel would not hold a group after that station. Why- it did essentially become a very light weight tube?
Round count- AR platforms... are they all limited to 20rds before they are to hot to hold a tight group?
Don't worry you will have your continued chance to call us 'liars and snake oil salesman".
We will be running a test on three barrels. With each rifle (identical as possible) weighted to the same value (at center of mass) regardless of barrel weight. One will be an ultra- light barrel. By many premises here (yours included) that light weight barrel should match ours round for round- harmonics, stiffness and heat does not matter. The test will be daily 5rd groups with a weekly 30rd group cool down for 5min and a second extended group.
You are welcome to bring your 6mm or 6,5 or whatever and put your groups into this sequence- let alone a gas gun platform. I will be happy to pay for your hotel and food costs.
I know what you will say... it is easier to attack, on a key board, something you know absolutely nothing about. NOTHING: back to the Second Area of Inertia and Heat Transfer. Though I forgot- you believe the light weight pencil barrel will hold with a standard bull barrel and our barrel.
