I don't think there's a need to get into the Devcon vs. Marine Tex vs. JB vs.... do a search, it's been covered ad nauseum.
Marine Tex apparently does have lowest shrinkage over time according to this article.

What Are the Best Bedding Materials? Speedy Speaks « Daily Bulletin
A customer of well-known gunsmith (and Hall-of-Fame shooter) Thomas Speedy Gonzalez recently asked Speedy about bedding compounds. Speedy offered some interesting advice based on long-term testing of various materials. Speedy favors Marine-Tex because it is very stable over time, while other...
I chose a different path years ago. Instead of bedding, I bore a hole for a 1/2-28 thread at the rear guard screw on the action side. Next, thread a stick of brass for the same pitch and screw it down tight. Now you have a tree stump sticking out of the stock. Mill it down close to the tangent point on the tang with a flat endmill.
Next, either surface it with a cnc or use a ground form tool with an appropriate radius. We just whisker pass it until it makes tangent contact along the entire length of the receiver. Proofing this is easy. Just install the action and begin to tighten the rear guard screw and check parallelism along the action's length in the machine.
I realize its not a means within everyone's reach, but its a whole lot cleaner, simpler, and robust than a gob of "magic whatever" lumped into the ass of a chassis stock.
Happy to help.

I recently tested a rifle setup, and found no detectable change in accuracy with bedding a good stock or chasis.
I really wanted to see a difference, with all the work, but the truth is, it doesn't help most setups that much.
However, I do like JB weld steel weld, for it's strength and durability.
