I have been scheming on making an aluminum tension barrel similar to the ones used by several 10-22 barrel manufacturers. I have a magnum research 17mach 2 barrel and love it, however the costs of a center fire barrel with the same technology is absurd. MR makes what appears to be a nice carbon wrap barrel, they just have lousy twist rates and caliber selection. This leads me to scheming on how i could do it myself, I am a fairly competent glass worker ( I am partners in a wretched glass 44foot seiner) but i don't think i could pull of a wrap job. I shot a buddies aluminum sleeved 22 and it shot on par with my solid stainless barres, which got me to thinking. Could this be done with a center fire? I feel confident in working with aluminum and the tension sleeve idea is something i think i could pull off. I have a few questions and would like the input of those of you (pretty much everybody) who know more than I. 1. Is there to much barrel warp when firing a center fire say a 6x284? 2. Will expansion and contraction in temperature be a fairly large problem on say a 20inch barrel? 3. Would electrolysis be an issue between the ss barrel and the aluminum sleeve? 4. Would it be better to do a tensioned barrel like a volquartsen or a pressed on sleeve like a tactical solutions? I guess ill start with those four.
