JB weld's info Properties (psi) Tensile Strength: 3960 Adhesion: 1800 Flex Strength: 7320 Tensile Lap Shear: 1040 Shrinkage: 0.0% Resistant to: 500� F
Devcon 10110 info Compound has an adhesive tensile shear strength of 2,800 psi and a Hardness 85 Shore D
So, JB claims ZERO shrinkage, which is impossible, but for the layman close enough. The devcon has a higher shear, and not seen is Devcon steel is also harder than JB.Devcon has a slightly better shrinkage number, but I don't have the info to post.
Is JB probably plenty good, I'd say yes, and chemically it is good for all gun solvents sans MEK, which both will be softened by.
BTW, epoxy is not all the same, many are terrible for gun applications, usually either too soft or too hard, and shrinkage is Brownells advertising method of suggesting their bedding compound is the best....and there are many poor epoxies for bedding a rifle.
I think Va'S gun will never know the difference.

Congrats dude.
Way to lead the charge into budget bedding.
Something clever here.

Da chit works.
Gotta couple/three more that need doing soon, too. The Mannlicher CZ550 is going to be interesting, to say the least.

A bit OT, but what's with the price of epoxy in recent times? Seems like it is skyrocketing. A basic Acraglas kit is pushing toward $30, and a Glasbed kit is $32.
Seems to me that it's been going up much more than general inflation, and has been for some time.

I use Devcon steel putty these days but used J-B Weld a few times. It worked well and those bedding jobs are still holding up nicely. The guy who taught me about bedding will only use J-B Weld and he successfully beds lots of rifles for lots of folks.
Now with even more aplomb

Va,
I use JB on all my rifles...but only on the tang.
Reason : I use Marine Tex for the lug area...that would be step one
Step two, next day I pop out the rifle and do the tang area after the front is cured. Because it is the tang, I only need a small amount of epoxy, and JB in the little tubes makes it a breeze to mix up a small amount.
Soooooo.....basically my bedding jobs are two part : lug area first, I build up the tang contact area with tape, so I leave some room for epoxy. Round two has me pull the rifle out of the stock, clean up the front end, prep the tang area for epoxy. I apply the epoxy to the tang area, replace the rifle in the stock and torque the front action screw, and only have a dummy screw in the tang hole. I believe that this method beds the tang area better while the front screw is torqued to the amount of tension that the rifle will be sitting in the stock. Obviously I use a torque wrench on my rifles.
Never had a rifle shift zero if I pull it apart and put it back together using a torque wrench.
Works for me anway.......YMMV.

Tony;
Good idea. I'll try that with the next one (J-B front/rear, though) and see if it makes any difference.
How many pounds are you torquing?

Dang, almost hoping it would stick just to jazz up the thread on the Campfire page. Couldn't think of a reason why JB Weld wouldn't work but JB Weld has been so abused it just screams BUBBA! to me. Nothing wrong with the product, just some of the things people try to do with it.

Well, I did 'bout [bleep] it up.
The bedding looks great.
J-B Weld up the front action screw hole into the action, though, didn't look so swift.
Thanks to Northern Dave and Sitka Deer for talking me down, and through the fix.
