HAM Sharp Shooter
To start with I shoot competitively for the AOA / Daystate team and love every minute of it. That being said the barrels in our guns are a good 10 to 20 points behind the leading competition. Being a life long athlete I hate losing and even worse I hate knowing even my best day is not likely going to be enough to win. Add that I've been a mechanical engineer for a long time and the tinkering began.
I bought a barrel tensioning device from Ben in AZ, it was good but only gave marginal improvements. Many carbon tubes and springs later I had a system that was worth a solid +2-3 points. Do the math it was not good enough.
I liked the carbon tubes and the moderation of the harmonics so I started work on barrel tuners. Found a doctorate level thesis on barrel tuners and started calculating the weight based on projectile weight, speed, diameter, barrel length, barrel thickness. Several prototypes later this began to give improvements to scores as well.
Enter my first Ghost with 28" 1:30 twist barrel. It shot pretty good in stock condition but not any where close to the needed scores to win. A number of prototypes later the first Harmonic Modulator, a carbon tube molded to the barrel with tuner on the end. With some heavy barrel polishing it netted a 5th place in AZ EFT and minus a shooter mistake in the 100 it would have been a solid placement. (this also could start another discussion of what the lands and grooves do to the pellet and speeds, like a LW vs liner design saw a 30 FPS difference in speed)
Enter my first barrel prototype with the Harmonic Modulator I went with 22 cal since I had bought a Fady Ghost which came with 28" 1;17.7 twist and their barrel tension system. It was BAD and the barrel tensioning was even worse, it could not shoot pellets or slugs. My design created an outer barrel with a competitors liner which I molded into the outer barrel and then added my Harmonic Modulator. (I will add pictures tonight after work) This was an instant success I won EFT in Idaho and took 2nd in Utah. Also in the 100 yard had to stop using my front rest and use bipod and bag and still shot a 231 while standing behind the table.
Knowing EBR was coming and some of the EFT targets would not go down with a paddle hit from the 22, I got a 30 cal barrel finished a couple weeks before EBR. It was shooting stunningly. EFT didn't go well due to a oring failure but with a fix shot a 240 in qualifications. Yes I shot bad in finals (could not get the wind read right) just a 218. These barrels are looking great. The 25 cal is now done and shooting better then the 30. I remind everyone that this is just buying liners while competitor knows I'm on the other side so you know I'm not getting the best liner available. My design strengthens the outer barrel and reduces the harmonics of each shot and results in a barrel that now gives me a chance when I go to competitions.
My goal is to begin selling the system, yes the cost is going to be high but not being a company my resources are limited and I'm fronting the entire cost of the design and manufacturing. The complete system, will sell for $1400 and can be fitted to a Ghost, Delta, Alpha. I can reduce the cost if you have a 700mm liner that you would like me to use.
I'm using this to get an idea of the level of interest so I can start ordering parts for the barrels. I have designs that can create 22, 25 and 30 cal barrel systems. You can also just get the barrel minus the Harmonic Modulator and just place the stock air splitter and shroud on. You can also use the barrel clamp as well but it won't work as well as the Harmonic Modulator frame block.
