    I was concern how barrel in my benchrest stock position almost touching one side and having huge gap on the other so I took stock out and got some pictures. It looks like right side is not cut proportionally to the left one and pillars do not support action.

    The pillars job is to give the action screws something non-compressable to tighten against. A proper action bedding job should fix your concern. Pillar bedding is a misnomer in my opinion.

    Pillars should come in contact with the action and the floor metal. and bedding is used to support
    all areas of the action that touch the stock.

    They are seperate but work together to improve the consistant fit of the action and prevent it
    from changing causing accuracy problems.

    With proper installation of pillars and bedding, a stress free mounting/mating of the action to
    the stock is possible.

    Pillars that don't come in contact with ether the action or the floor metal are not effective.

    It looks like wood needs to be removed before any bedding is done and the pillars are two short
    and need replacing.

    I will remove excess of wood, but the pillars, do they come out easy? I could try to drill them out. Maybe send it back, this is replacement I got for LRP. They say they checked it before shipping it to me...

    Mill out those pillars and do a proper bedding with properly installed pillars.
    There is no such thing as a one size fits all in the quest for extreme accuracy...

    Some factory pillars are simply a piece of tubing pressed in and can be removed by using a drift punch and tapping on it with a small hammer.

    If they are not radius's to fit the action they only touch in two small areas.

    Do a search on pillar bedding and Nesika chad has some great pictures of PROPER BEDDING.

    They do look like pieces of tubing and if they dont have any slots on eather end to screw them
    in they are probably pressed in and can be removed .

    I just pressed out a set just like them on a new stock for the same reason.

    They also look very short .

    if you look closely they have X mark on them, I think they did get in by something screwy :D they didn't really had any contact with action, upps got all the material taken away by dremel :D, but I'm leaving them in for now, I don't have new pilars to put it in, but I made them curvy so they'll hug around the action. Devcon, here it comes :D

    If you leave those original "Bolt Sleeves" (Pillars) in, you are making a mistake. JMHO
    If you are going to do it your self read the link below over, and over until you understand the whole process and then go for it.

    I am sure that I will get some disagreement, but in response to pillar bedding, I have a different approach. when one uses pillers surrounding the action screws to support the entire barrelled action-that is exactly what you have-support only by the minimal surface area of the top of the pillar. I feel that the pillar material and the bedding material should be the same-You cannot get bedding material and steel pillars to shrink uniformly. Have seen pillar bed jobs that glass bedding has shrunk enough to put all stress on just the tops of those little pillars.

    When bedding action, the stock material can be cut out 1" around action screws and chanelled to the recoil lug even going back to magazine cutout. This then is poured as one unit and nothing is going to 'shrink away' leaving a minute amount to support entire barrelled action. It is important to use a tough bedding compound (I use Bisonite steel) and not some of the soft bedding compounds that are available. Again, pillars should be the same material as the bedding and poured at same time.

    That looks like a Savage stock to me. If it is, get rid of the center pillar and the center bolt when you bed it. Use the front and rear bolts only. The center bolt doesn't do anything useful and will almost unavoidably cause a lot of stress in the action. Two points make a line, 3 points exactly in line is almost impossible to achieve.

    That's an easy stock to bed once you realize you need to get rid of the center bolt and pillar.
