I used this stuff on my M77 Ruger with great results, after 30+ yrs it remains exactly as it was when it cured. GREAT stuff!
My question is about heat. All epoxy is affected by heat, usually it will soften, and probably firm up again after cooling.
So I am wondering how much shooting it can withstand on a medium sporter barrel, 308 caliber? Has anyone ever experienced softening or repositioning of parts like the barrel once the gun got warm?
