I intend to use a wood laminated stock for a 505. Lots of recoil with 600 gr bullets. I have an extra, full size barrel lug milled on th barrel plus the normal action lug on a CZ 550 and two cross bolts. I will bed (combination of Brownell's Glas bed and Steel bed) and am thinking about adding pillar bedding as well. Saw this: http://www.firearmssite.com/glass_bed.htm and thought of I might add two more invisable cross bolts. One behind the barrel lug up front and one in front of the reciever lug. Broke one stock already. Pillar bedding going to add anything on a wood laminate stock besides weaked the wrist by adding a bigger hole in the stock? | ||

I always pillar bed if possible, it keeps all my screw slots timed properly and the end result is usually more accurate than a non-pillared rifle. It doesn't make the wrist any weaker but it does concentrate the added strength into one area instead of spread evenly throughout the wood, so in a catastrophe it might appear that it's weaker. I'm also a big believer in hidden crossbolts as well as visible ones. IMO a heave kicker needs all the support it can get, just good insurance.

There's not much reason to pillar bed a flat-bottom action in a solid wooden stock; it doesn't hurt, but it's not necessary. Now, in a softer sythetic stock I insist on it. John Farner If you haven't, please join the NRA! | |||

When glass bedding I also use the hidden cross bolt on stocks that don't have cross bolts. It's extra insurance, I have yet to have a stock crack. | |||

What John Said.  I sure would add some crossbolts As usual just my $.02 Paul K | |||

Over 100 years ago, Mauser proved that pillar bedding was superior for miltary use. Almost 50 years ago, Seely Masker proved that pillar bedding was superior for accuracy use. You guys can take your choice but I always pillar bed if possible, been doing it since the '70s and have never seen a reason to stop. Kinda like crossbolts, just good insurance.

Pillars don't inherently increase accuracy, they only increase repeatability if the action is removed from the stock. A stress free, stable bedding surface leads to accuracy, however it is achieved. If pillars were the be-all and end-all of accuracy, I doubt bench rest builders would deal with the pain in the rear of gluing in actions. Contrary to what some others have said, I personally think a good pillar bedding job is more critical in a wood stock than a quality synthetic, as regardless of what some would claim, wood is an organic material and by it's very nature will expand, contract and allow moisture and air to enter. A good pillar bedding job eliminates any movement. | |||

I am certaintly not in anyones league here as a gunsmith but can offer my thoughts as to why I pillar bed. My reasons are sort of on the same line as CAS II and that is dependability and repeatability. Putting the pillars in the stock does away with the wood compressing over time and affecting if the point of impact will change. The same tension amount stays with the guard screws over time. I never put pillars in a syn stock but have noticed the McMillan Edge stocks do have pillars in them while their regular stocks do not. My biggest fear is when I die my wife will sell my guns for what I told her they cost. | |||

Full Length bedding or http://www.savagearms.com/accuracy/accustock/ . Wood is what it is , sturdy and beautiful to a point!. When wood and metal marry there is sufficient reason especially with larger calibers to make that union a marriage made in heaven . Thermal expansion and excessive transmittable shock warrants reinforcing wooden bedding fibers , with a High quality synthetic epoxy and cross bolting or machining a full length insert similar too Savages accustock . As each of us know complete rigidity is the end result of our desire !. If the above methods are used I personally see little need for Pillars . But then again I'm not a gunsmith only a glorified Engineer !   | |||

Epoxied in two external cross bolts today. Then cut and laid in three more invisable cross bolts between the two barrel lugs today. Only added one stock channel but used the other two CZ had cut previous. Gotta let that dry before I bed the action and make the final decision on adding pillars or not. Likely I'll add them as it is so little effort to do so. I appreciate all the comments, thank you. Here is another question for you? Forarm is all of 8.75" long with a 21" barrel. Just to make things easier I am thinking about bedding the entire barrel and no free float, as the barrel lug is only 2.75 back from the forarm end. Do you see any down sides with that idea? | |||

In the FWIW catagory. Steel bedded both the reciever lug and the barrel lug. (custom .505 cal. CZ) Then went back and added glass bed to fill in the gaps with the additional hidden cross bolts. Multi day job to get the epoxy to dry each time. Found the Mauser style stainless pillars from Brownells easy to drill out the stock for, then cut and glue in. Perfect pressure fit once done drilled, which I did in seconds with a electric hand drill and a bit matching the dia. of the pillars. Literally a 20 minute job on my Magnum CZ 550. | |||

Joe, if it is the steel "pillar" in the rear guard screw hole you are referring to I would raise the BS flag on that one. That steel ferrule was only used to inhibit the possibility of the the rear guard screw from compressing the wood from over tightening. This was a good thing in itself but often, with the ferrule being not secured in the wood, As what a real pillar bedding would do with bedding material, did not contribute to holding the rear tang against the wood; it would cause the action to float there.

Pillar bedding was easy.  Combo of Steel bed on the barrel and reciever lugs and brown colored Glas bed in the barrel channel not so much.  Internally reinforced rear cross bolt.  | |||

Jim, all the military 1898s I've stripped, except one, have had their rear steel sleeves fixed so tightly in the wood that I've had to fab a special shouldered punch to remove them. I've seen one or two late-war laminated stocks (not mine) with loose rear sleeves but of course I was referring to the majority, the ones with tight sleeves.
