NeuRon: A few more questions, if you don't mind:
Your questions help guide in my evaluation, thank you for these relevant and important questions. The power of the group is greater than invidual.Do you just plan to purchase the added baffles to fill the rest of the space, in the shroud, that the 17" barrel will leave? What are they, an inch/baffle, so 3 baffles?
I plan to get whatever is require to replace my barrel from Jim Gaska. I supply money and he gives me stuff which with a screw drive and allen wrench I can quickly install. The number of baffels is up to him but I a little indefinite without some further tests. I think the answer now is 2+ baffles to fit inside the existing shroud.Have you given any thought to trying to secure the baffles to each other (metal-backed ducting tape, perhaps?), in an effort to keep them aligned during reassembly? Do you already use a wooden dowel-rod to keep them aligned during reassembly?
This is unknown at his time as the final baffle is completed. There are pieces and ideas some untried but no final productWill you just replace all baffles with the newer, .25 size or enlarge the holes in your .22 baffles?
I hope to do nothing and Jim will work out these details. .25 size baffles though may not suppress the report as effectively.
Will you just enlarge the plastic end-cap on the factory Mrod barrel to fit into the larger diameter LW barrel, or do you think it might not be needed with the additional diameter of this LW barrel?
Again, this is a question for Jim Gaska after he has the first generation product completed. I would hold there would be an end-cap to keep the clearance clean as the clearance is less than half of the previous one. But the barrel should stiffer than shroud now. The previous barrel was not and that ultimate creates variations which turn into accuracy in the long term. A precisely reference stiff barrel can be consistently accurate in a changing world (shock, temperature, time, etc). The angle of error of concerned is a small fraction of a minute of arc. This requires extreme measures like heavy stiff strong barrels. I think that's all. You have me pretty well convinced to go with Option #1 (17" barrel, additional baffles, stock shroud).
I think you could call option 1 the "the extreme accuracy pest plinker" with current medium low noise maintained and option 2 "the magnum extreme long range shooter" with possibly a minor cost in grouping accuracy and noise but more fps for range and energy for target impact. Option 2 has competition from bigger calibers. Both options require many small compromises in the pursuit of accuracy. Both are risky but $200 is not an unreasonable father's day present. I think you like I probably are tasking the most appropriate risks pursuant the goals best matched to our desires. I hope it works out well for us.
I would buy a Rouge but I cannot use it in my back yard. I not shoot very much but it is another interesting optimization of design and it uses new materials and components for air guns such as an electronic trigger, valve and computer controlled energy regulator that combined with an advanced digital electronic imaging scope that knows where is and what is doing to augment the shooter would be awesome. The minimum sensible range of the Rogue is too long and the power is more than I need. I stll may get one though if I fail to remind myself of these issues.Update from airgunbliss on the Yellow forum:
The barrel is 21in long, and 16mm in diameter. I weighed the stock barrel at 285.7g. The barrel from Jim was too heavy for my scale. My scale goes up to 650g.
I believe is a non completed prototype of for option #2. The current barrel weighs 0.63 lbs and the 16mm 21" prototype weighs more than 1.43 lbs or more than 2.3X more (~0.8 lbs). My rough guess is the long barrel option would be nearly a pound (16 oz) more and the 17 in barrel (12 oz) more than the current barrel. It is heavy for sure but hopefully very stiff and stable as well.
And news on option #2 purchasers from Jim Gaska on vacation
Considering the increased sound volume caused by the larger diameter barrel, I will be happy to substitute the shroud mounts for a 1/2-unf clamp-on adapter for the end of the barrel. Cost will be the same as the shroud mounts, or you can add it for $20.
