Question about bedding a Featherweight
« on: December 13, 2004, 05:32:04 AM »
I've read the post about relieving the pressure on a Remington, but I wanted to start my own post about an upcoming project I'm thinking about.

I have a Winchester Featherweight in 300WSM that I've had for about three years.  I've tried several different loads with this gun, and had accepable hunting accuracy of 1.5" groups with some loads.  I'm thinking of changing the bedding this winter.  

This is a pencil thin barrel, in a beautiful walnut stock.  I want to keep the stock, but improve the bedding of the action and the barrel, thereby hopefully improving the accuracy of the rifle.

Now, my question is...where do I start?  Should I free float the barrel first, then pressure bed the action and the barrel?  What do these lightweight barrels like as far as bedding?

There's no pat answer for what a certain rifle or type of rifle will like.  They're all individuals, still I've found that sporter weight rifles usually shoot best with some pressure.  I believe it's one of the reasons Remington M700's have a reputation for being accurate(only one factor I admit).  I usually remove any material touching the barrel as a starting point then bed the action.  The action is then bedded with no tourque at all.  When the action screws are loosened there should be no detectable movement of the metal work in relation to it's stock. Bed the front receiver ring, including behind the recoil lug and about 2-3 inches of the barrel shank, also pour a pad under the rear tang.  Be certain the bottom metal doesn't bind with the action and relieve the bedding in FRONT of the rcoil lug.  Also the recoil lug should be clearanced at the bottom. Touching at that point can adversely effect grouping.  Only when the action is properly bedded can a correct pressure point be added.  I much prefer AccraGlass gel and add aluminum powder to it only for the front pour.  After the action bedding is complete you may pour pillars (or glue in metal ones) to make the bedding a bit more permanent.  Then one can experiment with pressure points and perhaps even full length bedded barrels..  I've a 6.5x55 Swedish Featherweight that I'm getting ready to work on for myself..  Good luck with yours..

I have had the best results bedding the whole action and as Gunnut 69 said do not crank down the screws.   I tighten them slightly, slowly and evenly, but not much more then slightly firm.    I guess that is a good way to describe it.   At the same time I also bed the chamber area of the barrel and leave the rest floating.   A clay damn is a good way to keep the bedding from oozing too far forward along the barrel channel.    With the Winchesters make sure you get lots of release agent inside the front receiver ring as that is not a blind hole and glass bedding in the locking lug recess and chamber is hell to remove with out the release agent.
    Another hint, if you screw long Q tips into the guard screw holes before you put the action into the stock it will help.    When you pull them out to put in the guard screws it will clear out most of the bedding compound.
    Also instead of release agent on the guard screws I have found it works to heat the screws and coat them with candle wax, this gives some clearance and ensures they do not get stuck to the bedding compound.
There is no such thing as over kill!!!!  :-)

Thanks guys.

So, you free float the barrel first, right?  Then bed the action, and maybe a couple inches of the barrel.  
Question:  I probably shouldn't take much out of the barrel channel if I'm going to bed the action with very little torque on the action screws, right?  If I take too much out, I'll end up with a huge gap between the barrel and the stock after I bed it.  I know this won't impact accuracy but it will probably look like crap.  

Comments?

More or less.  The barrel needs just enough clearance to allow a $1 bill to pass..  this effectively removes any pressure that may alter the geometry of the action bedding.  The action area is relieved to allow the bedding to bond to the wood and provide enough thickness (especially behind the recoil lug) for strength purposes.  I like at least 1/4 inch behind the recoil lug.  The front receiver ring should be supported about 1.2 the way up the sides and completely under the bottom, this pad should also include the rear of the barrel about 2 inches or a bit.  Also pour a pad of bedding under the rear tang.  None of the bedding should be exposed when the metal is installed in the stock.  A bit of oil based modeling clay rolled nito a rope and laid across the barrel channel will contain the bedding compound.  When the action is CORRECTLY bedded there will be no discernable movement of the action as a single bedding screw is loosened or tightened.  On the M70 action the center screw serves no purpose other than retaining the front of the triggerguard.  If it is tightened very much at all it will warp the action causing grave accuracy problems so screw tightness is something to watch.  The front screw is tightened first and firmly, the rear next with a bit less torque but still tight.  The middle screw is tightened just enough to retain the front of the trigger guard and supress it's movement.  Where ever bedding is to be applied remove wood equal to the thickness of bedding pad needed.  the front pad will be a continuous piece from the front of the magwell opening to several inches in front of the receiver ring.  When done the action should have no tension and no movement when the screw are loosened or tightened, then the rifle can be shot for accuracy.  If all is well no more has to be done.  The barrel will be free floated.  If pressure is desired a temporary pad can be made from a plastic credit card or something similar.  Cut a piece and insert it into the barrel channel such that it covers the bottom half of the channel for a distance of about 1/2 inch. Thichness can be altered as can position to fine tune a bit for the sake of accuracy. When the right place is found a pad of bedding can be placed there by using the clay to damm up the channel on either side and a plastic shim to provide the correct thickness. Be certain to read and follow all directions carefully and use plenty of release agent,,,I'll say again'USE PLENTY OF RELEASE AGENT"!!!!!!   The bedding material is a powerful glue and if it bonds to the metal your stock bedding job will be permanent.  They can be seperated but it's a tramtic procedure and release agent is a good preventative.  I prefer wax as a releaase agent over the skin forming agent provided by Brownells.  The modeling clay should be used to plug any recess where the bedding may intrude to form a mechanical lock with the metal, i.e. magazine wells, around the trigger assembly, etc..  After the pour is made allow it to set to the rubbery stage and using a plastic chisel (sharpen an old toothbrush handle) cut away any overflow.  It is easy to remnove now but can be a problem later.  The plastic chisel won't damage the finish easily but will still cut the bedding..  If the metal is being difficult to remove a visit to a deep freeze for a few hours can break a minor bond but will accentuate a mechanical bond..  To falitate removeal of the metal work apply several layers of masking tape to the front, sides and bottom of the recoil lug before applying release agent.  This later removed from the bedding compound(it will stay in the recoil lug recess when the metal is removed) and the resulting tolerance will allow the metal to be easily taken out of the wood while preserving the tight fit between the rear of the recoil lug and the bedding..  Read this all again and if there are questions ask..  After the bedding is poured is a really bad time to find a problem..

Thanks guys.  I'm going to print this off when I'm ready to start, and have it next to me at all times.  I'm sure I'll have questions when I get the rifle apart and get ready to go.

Thanks again.

Glad to help.  When using polyester bedding compound preparation is everything.  The material sets up based on time and tempurature and there is little you can do to slow it down.  Get everything ready before mixing the compound and a trial fit of the metal(prepped for bedding) is a good idea.  Apply the release compound should be after the trial fit to ensure it's not damaged.  A couple of tips. When pouring the bedding into the stock coat the metal with a bit and the wood where it is to go with a bit also. This ensures a good bond.  Then the rest of the material is poured into the inletting as a row down the center.  This will be forced to the side as the metal is lowered into the stock, eliminating most trapped air that will create voids in the bedding.  Also icecream stick and tongue depressers make ecellant tools and are readily available at craft stores..
