I have not bedded one in about 5 years, I used to use Acraglass or Bisonite.

My Australian gunsmith buddy uses DEVCON, and swears by it.

What are you guys using and why?

The most available/common are
Devcon 10110
Acraglass
Marine Tex

I use devcon but that little jar will dry out if you only do one stock a year which makes it one of the more expensive options but its pretty thick and easy to handle.
Marine tex has the lowest shrinkage rate among them but it a bit more liquid and harder to keep from flowing.
Arcaglass is probably what Ill try next if my devcon is dried out already since I can get it in the cool little easy to use hotglue gun type dispenser.

I use devcon 11410(wear resistant). It’s what my mentor used. Looking at the specs, all the appropriate devcons are pretty high quality materials.

I bought some Marine-Tex recently, which i’ll try out soon. Seems highly regarded. ya

Your preparation and technique in doing the job will be the most critical factor imo.

I have used Devcon 10110 in the past but the last stock I did I switched to Marine-tex grey and will be using it from now on.
Both give excellent result but the price of Marine-Tex is about half that of the Devcon that I only used about half of and it was mostly set up by the time I needed it again.

I tried Acraglass once but much prefer Devcon 10110. It works great and I haven't had a reason to change.

I now use Marine-Tex based on a recommendation from my rifle builder. I buy the 2oz kits because I don't bed many rifles and the shelf life isn't great, a 2oz kit will bed 1-2 rifles. I've used Devcon in the past, and had no problems with it other than the hardener drying up on the shelf.

Devcon Fasmetal 10 D19770, mix it up and add some black dye so no one knows what compound you're using (or printer toner if you're a cheap ass) spread it thin on a sheet of glass with a putty knife & let the bubbles settle out, then scrape it up with the putty knife and scoop it into the inlet. Use your wife's hair dryer to get the compound thinner and use some popsicle sticks to poke remaining bubbles out. Gotta keep from going full retard with the heat gun or you'll cure the epoxy before you even get the action on there.

I use Pro-Bed 2000 from Score High in Albuerquerque , Charlies shit is the best I've used so far!
Easy to use plenty of time before setup, as always with anything preperation is the key to success!

Marine- Tex gray. Long work time, forgiving, easy to file and work.

Used them all over the years. Won't use anything other than Pro Bedding 2000 now. Cheap, impossible to mess up, and you can customize you're texture. I liked Devcon and Marine-Tex prior. Switched mainly do to cost.

I have used many different ones but I keep going back to JB Weld. I have some rifles that have been bedded with it for 25+ yrs, no issues. If I'm in a hurry, I use JB Kwik most of the time, just need everything ready to go.

Easiest to use: Devcon plastic steel putty. Not runny, forgiving texture, easy clean-up as it hardens. Cons: Unused dries out quickly.
Hardest/least shrinkage/best value/fairly easy to use: MarineTex

I've bedded 2 or 3 stocks with JB weld and 1 with JB kwik. It works; no complaints yet.

The secret to any bedding system is in two key sectors:

1. Don't compress the stock material
a. If you have a composite stock with heavy, fiber-reinforced epoxy (on manners, this is dark grey color) you don't need to worry about pillars
b. If you have an aluminum chassis where the dead-bottom 6 o'clock portion of the receiver makes contact with the aluminum, you don't need to worry about bedding.
c. If you have light colored soft foam or wood, you need pillars

2. Support 3 areas on the bottom of the receiver
a. A ring around the front action screw
b. A ring around the rear action screw
c. The rear of the recoil lug, squarely

Do those things and you should never have a problem. Don't put any goo in the stock until the action sits where it's supposed to, stress-free. You'll notice good chassis systems (Manners mini-chassis, for example) do this exactly. Some simple V-block chassis do not-- They have a gap between the bottom of the receiver and the bottom of the V block-- and are much more sensitive to action screw torque & repeatable POI removing/reinstalling the action.

It doesn't have to look pretty, and it doesn't require any more epoxy (usually) than will fit on top of a quarter.

My 25-06 was bedded with accraglass over 25 years ago and it was still hard as a rock when I pulled it out last winter.

I know it may not be the most popular, but I'll have to say it does work and holds up over time and cleanings. (That barrel wouldn't shoot clean or dirty, 5-40 rounds were the good ones then groups went haywire, 60's era factory 700 action and barrel).

Either normal or kwik (5min) depending upon your time etc. I normally use kwik because everything is ready to go and literally within 10 minutes, I'm popping the action. Soft? Not a chance. Acraglass is fairly soft. Devcon putty is good but JB is cheap and works well. Make sure your parts are prepped well with release agent. My favorite is a spray made by Wurth HSS-K. A synthetic spray "oil" that is VERY adhesive, withstands high temps and pressures. They just come apart, best I've ever used, makes shoe polish look like junk. Also very good on bolt lugs.

I've experimented with many products including jb weld products, pro bed, devcon putty, acra glass, marine Tex, and some expensive stuff. What I found is pretty much all of it can be used and do a decent job if you have good technique.

As far as shrinkage goes and how it finishes up devcon steel putty is great as well as pro bed although I personally like to add in silica powder to thicken the pro bed and make it less runny. Those would be my first two choices for common epoxies.

Someone I came across that is my number one pick but extremely expensive if you have more than just one gun to do is Huntsman Araldite 2014 High-Temp Chemical-Proof Epoxy Gel. Nothing I've used finishes as nice as this stuff, it's extremely strong, very great to work with. While I find devcon to not shrink and give me nearly no deflection the araldite stuff is even better. Last time I ordered it I used Amazon and it's about $40 for a 2oz tube (ouch).

Titanium Devcon with a Marine Tex coating is really strong, water proof and appealing to look at.
