Bedding with hardware store types of metal epoxie.

One of the reasons Acra Glas is recommended by Brownells is that it has no expansion from different temperature extremes, or is very low. I’m not sure how devcon is or marine tex but either way its probably very low when used sparingly.
 
I've done a few rifles with JB weld, seems to work good so far. It is very runny though, so can be a bit of a pain. It can be easier to work with if let to set up for a few hours first though. I've had rifles in and out of the stocks with no change to point of impact, and shooting them on both hot and cold days with varying humidity, and still no change. Not bad for a wood stocked rifle.

That is an interesting thought that "Devcon" is the "right stuff" to use for bedding rifles. Brownells would disagree - they sell Acraglas and Acraglas Gel. I read that USMC Armourers use Marine Tex. There is multiple - many - kinds of "Devcon" - the stuff on the shelf here is "Plastic Steel Liquid (B)" - No. 10210. I also had some Devcon stuff "Plastic Steel Putty (A)" or similar name - I forget the number - that got tossed as it set up in the containers - as I think this Liquid stuff has also. Both were two part - Resin plus Hardener to mix in specified ratio - the Resin set up in the container before I got to use it. There is an expiry date on the box - "Use by" - and they are not kidding about that!!! Others on previous posts on CGN have recommended Aluminum bearing products, not steel bearing. So hard to say what is the "right stuff" to use.

Brownell’s would disagree because they don’t sell it. Who would have expected a retailer to recommend the products they stock in store? Lol. Acraglass is a great product, and I wouldn’t hesitate to use it, but Devcon is, IMO, better. Plus it’s available locally here, and it’s super easy to work with. As for the dust in it, aluminum, steel, titanium, etc. the only issue with the material is a potential for galvanic reactions - which is silly, but use steel just to be safe.

As has been mentioned, JB Weld can be runny and hard to work with. I ran across this stuff and was wondering if anybody had tried it. It’s on my list to give a try. JB Weld SteelStik Steel Reinforced Epoxy Putty Stick

Not sure, but it might solve some of the issues. Like I say, it’s on my list to give a try.

I've tried that stuff, and it works good if you've got a big void to fill and a good escape route for any excess. I thought it was too thick to flow properly into areas where a thinner coat was needed, and it also cures very quickly, at least the stuff I used. I had put it in the bottom of the pocket where a recoil lug was to sit, and ended up not being able to get the action far enough into the stock I ended up sanding it back out and then doing a skim with the regular JB weld after. I could see it being good somewhere like a pad under the barrel in the barrel channel where it's got lots of room to ooze out. That would save messing around with building dams from modeling clay.

I think the main problem with products like JB weld is the short work time.
Products like devcon and marine tex have a way longer working time.
Devcon 10110 has a 45 minute.

Marine tex has a 15-20 minute working time.

Acra glas has a 25 minute work time.

For a noob like me, a longer time for the epoxie to set up the better, since I haven't bedded a rifle before it gives me plenty of time.
 
JBWeld is heavy. I did my wife's 783 (mostly to try doing it). Accuracy increase was spectacular, it's actually an MOA rifle now without any other mods. But I made the mistake of sort of filling the forearm instead of just making stiffening strips across with the JBWeld. Just something to keep in mind. If you're doing a wood stock without big voids I don't assume this will be an issue.
 
MCM - I think you have misread the Devcon data sheet. There is absolutely no way you can work the Devcon after 5-10 minutes, for the purposes of bedding an action. I dont think JB Weld is any different. You gotta work quick! Suggest you pick up some product and see for yourself.

I just bedded a stock with JB Weld, and I waited for 10 minutes, so that the material became less runny. It worked out well.
