Ok so I have some more questions after researching some other methods that bench rest shooters use that we can employee in our project.
Looks like some of them have taken a liking to all kinds of homemade methods, but one in particular that caught my interest was a short blast of CO2 to the barrel. Now the first thought is, won't that damage the barrel? Science tells us heating and cooling to quickly causes stress to the metal and microscopic cracks, fissures, etc etc can occur and make the material become brittle.
However, it would appear most people shooting bench are not getting the barrel temps nearly high enough for this type of reaction to occur. Its one thing to drastically drop the temp on a barrel that has had a hundred rounds from a beta mag dumped through it vs. someone who fires 5-10 shots.
Can anyone comment further on the science of this?
I was thinking C02 cartridges are readily available at local retail stores for very cheap ($6 per 15 on average) and I could rig a mounting and puncture system with some tubes to basically inject the C02 inside the shroud and onto the barrel.
...or taking the system as far as a thin jacket for the barrel and the C02 is injected into a hollow space between the jacket and barrel.
I have a lot of available space on the shroud, so mounting has all kinds of options (think shotgun shell holders, but for C02 cartridges and a puncture system operates by a twisting knob on the bottom of each that pushes it up into a nipple, the nipple is hooked to a tube, the tube sends the C02 to its destination.
Thanks for any edumikation you can provide me.
