Why is Devcon 10110 the gold standard?

[twofewscrews]

I recently bedded my Hogue Overmold stock on my 10/22 using JB Weld and posted my progress over on a popular rimfire site. The ultimate goal is to rubber bed the barrel and see if it produces tighter groups then bedding and free floating the thing alone. Devcon 10110 was suggested instead but it was already done. From looking at other forums it seems Devcon 10110 is the gold standard. Why?

As far as I can tell:
Devcon 10110 (5600 psi) is only 580 psi stronger then JB Weld Original (5020 psi)
Devon is rated to 250 degree and JB Weld is rated to 450 degrees
Devcon shrinks such a small amount its not worth mentioning and supposedly JB Weld does not shrink at all.

I'm not advocating for JB Weld over Devcon, this is my first time bedding a stock, I just want to understand why Devcon the gold standard?
Does it last longer or perform significantly better then other bedding compunds such as Marine Tex or Agraglas?
Is it easier to use based on pot life and consitency? . . . but with regard to performance there isn't really a difference between Devcon, Marine Tex and other brands?

What am I missing?

I’ve used both Acraglas and Acreglas Gel, Devcon and JB Weld (JB was not used for bedding). I can’t say I’ve seen any particular difference in performance. As far as consistency, I liked working with Devcon, but then I used their products in industrial applications and was used to it. I will note here that I’ve seen Devcon crack after years in use with mounting big 1,000 horse motors (big improvement over poured babbitt) but that wouldn’t be applicable here. Really, Acraglas in red or green has been as good to use. I do prefer thicker most of the time.

I build a punch list before I bed and am very organized before I start. To do otherwise invites big headaches. Pot life has not been an issue. Devcon is a bit harder to clean up IMHO, so it pays to not use too much and get sloppy. PITA.

You can dye Acraglas which is nice.

I’ve got rifles bedded in Acraglas and Devon that are older than I’d care to admit. None has degraded as far as I can tell.

I’ve not bedded a .22, so can’t comment there other to suggest pillars If possible. As far as rifles, I do both pillar and action bedding. I really appreciate pillar bedding. Some of my early work from the 70’s weren’t pillar bedded, and I’ve since gone back and added the pillars. But, you can only expect so much from sporter-type tapered barrels. You take out all the slop you can and go with it.

I think it all depends on the job you have. Sometimes thick, sometimes thin. I’ve seen some poo-pah about JB Weld, but it’s worked for me. I mainly use it to set scope mounts. Quick, easy, works great.

I’m going to come right out and say that “acra-GLASS” and “devcon STEEL” and “MARINE tex” just sound sexier than “epoxy.”

I sporterized a 1917 Enfield back in the '70's and used JB Weld for a bedding agent. It shot MOA with Remington 150 Corelockt ammo then and recently did the same with some 150 gr. Hornady ammo as no Remington was available. I suppose close to 50 years of age proves it works well. I used acra-glas to bed another 30-06 a year before and it is still good. Since then I have used devcon, gorilla glue, and one other brand (forget the brand) of epoxy with no failures.

I can show you a set of hand rails glued to concrete with devcon epoxy in the late '80's that are still in place plus I glued a door stop to concrete on my storage building even earilier that has had some hard use and is still there. I really haven't payed any attention to numbers but it has all done it's job quite well.
