Why Proper Bedding is Important?

Numbers look good but what they don't show is what happens with vibration and a rifle has plenty of that. AND there is no data based on how thick the material is.

Read the side of the box (Devcon), they state that this stuff should NOT be used in a thick application without internal reinforcement. Make a strip 1/8" thick and bend it compared to a piece of wood.

I know which one will fail first.

I have seen enough bedding break apart in Semis and boomers to know that this stuff is not designed to last in a thick application. I am sure there could be a formulation that would but that is not something I have access to.

Wood is "soft" BUT its resiliance has been proven in millions of rifles over 100yrs. Perfect, not even close but not bad either.

Now couple these traits with a THIN coating of bedding and now you make the most of the materials involved and the sum of the parts is MORE then what each can provide.

Why epoxy bedding can also be so effective with a foam cored composite stock. Way better at handling high freq vibrations and can help the epoxy bedding from shattering.

So, it is not that bedding compount is bad - far from it. This stuff is a god send. Just use it the way it was designed to work best and rifles will shoot itty bitty group.

so you bed all your HS Prec stocks?
i recall reading in a post by HS Prec that they highly recommend not bedding their stocks. im curious as to why they would say that?

Answer the question yourself - just remove the action bolts and see how the action fits in the stock. Applies to any rifle and any stock.

If it fits as in the first video, bedding may be a good idea.

One of the best fitting, believe it or not, is my Savage EDGE/Axis. Yes, the fit is good.

Another was a Tikka T3 Laminated stock I was commissioned to bed. The fit was so good, the epoxy was translucent from being so thin. NOW that is fine inletting.

There are many products promoted as the end all. The key is do they perform in the real world?

YMMV.

So it is bad to have a steel impregnated epoxy bedding job but OK to build the rest of the rifle out of plastic? :D

Which is better - a fork or a spoon?

Use the right tool for the job and use that tool as it was designed to work.

Remember that steel impregnated epoxy is similar in how you would compare sandstone (epoxy steel) to Granite.

The modern fibre reinforced plastic can be made BETTER then other conventional stock materials and methods.

As the barrel nut and floating bolt head is changing the way rifles are made, new molding methods will elevate the "plastic" stock to the way it SHOULD be made.

Anyone make a alloy framed handgun anymore?

Go check out a promag M1A or Nomad stock and make your own decisions.

The times, they be a changing...

The design of the MDT chassis negates the ability to bed it in the conventional sense. The only option is to glue it into the chassis.

I don't agree. But, am certainly open to your thoughts as to why glue-in is the only option, especially in light of the pictures and commentary below:

By bedding up front and on the tang, I have at least:
- reduced and uniformed action distortion when it is torqued down.
- uniformed / perfected the lug / chassis interface.

However, you get a tight fit, it's all good.

Do you grind out the stocks like the "road to precision" guy does? Is it necessary to do so?

I try and remove as little stock material as possible as I want that material to support the bedding material.

Most modern stocks already come with very generous sizing so taking more material out isn't helping my install.

Again, stocks vary, techniques vary. Just do what is needed to get things supported and well locked up.

Good video's, Really shows the importance of bedding on that one. I plan on bedding my savage mark II rimfire into a Boyds stock pretty soon here. Devcon epoxy steel seems to only be available here in Kamloops in 1 LB amounts. Way more than I need. Are you saying that there is a twin tube syringe from LEPages at Can tire that is comparable to Devcon? Is it just an epoxy or is there steel in it as well? Basically I am wondering if I can use this as a devcon alternative? Or the Lepages marine epoxy. And turtle wax or shoe polish as a release agent?

either will work fine. devcon is 70 per pound. i 've used kiwi neutral shoe polish with success, but now use redding imperial die sizing wax.

I would love to bed my MkII but there really doesn't seem like a whole lot of space to put the bedding compound inside the stock and around the action.
 
Work within the operating parameters of the bedding compounds you want to use and you will have good success.

Some products are NOT designed to function as a thick layer.

Check the manf guidelines and you will have your answer.

What's wrong with quality hardwood?

For foam filled composite stocks, they usually suggest large load bearing pillars to take the recoil forces off the foam. I am unaware of any expanding foam which will offer a solid backing to anything.

So it's pretty, doesn't do anything more than a stock with less bedding, that hasn't been cut out extra big for more bedding compund. Come on Chuck..
