The Shot You’ll Never Forget Giveaway - Enter To Win A Barrel From Rifle Barrel Blanks!

A number of years ago I was in Texas helping their hog invasion. I had taken a 30 x 44 rifle that started life as a hunter rifle benchrest gun. The fellows and I had taken a few hogs and decided to make a gut pile a ways from the trailer we were staying in. We drove down the side of a wash out on a two track and eventually dumped 5 or 6 tree size plastic planter buckets of entrails and hides in a pile. That evening they dropped me off at a blind on the other side of the washout. Far enough away that when vultures landed on the pile we had put out earlier I could not see them even with 10 binos. While scanning the pile I caught movement wyle coyote trotting down the two track on the far side from me headed for the pile. Turned my scope all the way up, stuck the gun out the window, lead by two mil dots, held over by one touched it off. Lost eye relief, re-qgained it just as the swack was heard. Couple hours later when they came to pick me up they said that the they heard me shoot. I said I shot a coyote over by the guy pile, shared the aforementioned story. They all scoffed no way that's pretty far off. So we drove around the washout the whole way they kept saying no way you hit anything over that far but after 5-8 minutes of their taunting we got over to the pile and there the coyote was mangy but dead 30 ' from his fill of internal organs. Later we figured it was about 450 yards. After a couple victory beers I told them how lucky that shot was. Remington 78 trued by Jim Borden rock creek 14 twist barrel, Larry Smart drilled in radial brake, 125 nosler BT, 39 gr H-322, jewel trigger, Leupold 3-10 tactical mil dot reticle target turrets. Still use that gun & have loaned it to a young lady on my road to use for deer.
Unfortunately one of the special fellas that took me hunting there Danny has passed. Thank you for promoting me to look through the photos of that hunt and the fond memories. God bless.

You said it started as a Fender Strat? If you will notice, the cutout in the body on the bottom side of the neck extends all the way back to the 21st fret. Your body/neck intersection stops at the 15th. Either way, nobody’s playing anything above the 15th on your design. I’m not saying that’s unacceptable, it’s just the trade off you made, esthetics vs playability. All those frets above 15 (maybe 16 or 17) are unusable.
Is bedding the AR barrel a myth? What's the best way?

So this reads like you have tried every method mentioned. Is that what you are asserting? What's your average group size for a silicone bedded barrel vs locktite vs epoxy bedding?The 2thou" I mentioned is air space that would happen if some goop (wax) on ID and OD is just 1/2thou" thick and that goop disappears somehow. That 1/2 thou is on the radius of ID and OD, so it's x2 (dia) for ID and OD , where ID gets bigger and OD gets smaller, so the net sum is x4, or 0.002".
Most goops don't just vanish though.
620 does carry decent temp ratings, the Henkel tech doc shows it to about 250C 482F(max) and holds about 68% strength at that temp, and holds 100% at 170C 338F. It actually achieves more than 100%(@28C) between 29C to 170C, weird but that's what we get from chemicals.
We know the aluminum grows with heat, so we would like the goop to do the same.
Coefficient of Thermal Expansion (x10^-6)
620 - 80
Silicone - is near 200
6061/7075 - 24
Although the goop may expand more by CoE than aluminum as temps rise, the goops' duro hardness goes down, less resistance to movement. Since goop layer is magnitudes smaller than the aluminum and steel, the net growth of goop expansion does not keep up with the metals.
With the JB Red silicone, I don't need a dowel or do any banging on anything, I can just secure receiver and pull out the barrel with a little muscle, the thin silicone will shear with "small" force, from there things clean-up easily. I don't get that experience from using 620 or waxed epoxy. 620 and epoxy have high strength in both shear and tensile, perhaps a wax release layer with epoxy lessens the force needed.
Silicone, 620, waxed epoxy, just epoxy, are all valid choices, but each has Pros & Cons. I'll bet on 620 and epoxy holding bbl tighter, but in same bet I bet ya the overall gains from the bedding diffs (epoxy vs silicone, 620 vs epoxy, etc) are lost in ammo/shooter/bbl.
Note: if I previously mentioned the loctite 680, I did mean 620. 680(green) is a lower viscosity item and it does not have good temp chart like 620 does.
