    two questions;
    1) have you ever actually seen stock splitting anywhere on a gun? I have not.
    2) what is the basic cause of stock splitting?

    I can fix a split, but the underlying cause is what is getting me. I suspect a loose connection between the breech and stock via a loose breech bolt.

    Poor fit of the wood to the action can leave a stress point which will cause a stock to split. I have had it happen. Also on heavy calibers the recoil lug can eventually cause enough stress to split the stock which is why you see cross pins in some rifles.

    Can you define heavy? And would at what point, or at what chambering, would a lug be necessary?

    most all rifle have a recoil lug. some it just prevents any movement fore or aft. but on some rifles, it does help to arrest recoil and transfer it to the stock. the chambering is irrelevent, since even my 17 HMR has a recoil lug. even my 204 Ruger has a recoil lug.

    there are many different things that can cause a stock to split or crack and recoil, or heavy recoil is only one of them. poor wood to metal fit as JTJ mentioned is one. defects within the wood itself is another cause. age of the wood can cause it to split or crack.

    I agree with what he said up there- poor fit wood to metal. Rarely, poor design. Older firearms, excessive oiling, which drains down into the wood right behind the tang, softening the wood.

    I had an old mossy hangfire drawing down on a grouse on a really cold day once, went to draw back and it went off, flew 5' behind me and broke the stock! Screwed, Doweled and glued it and have used it for 35 years since. That was my fault not the guns....

    A common cause is bad wood. Especially highly figured wood.

    Another is physical forces the stock was never designed to withstand (using it like a club or falling on it)

    Another is as said above improper fit.

    Another is a big change in climate. A stock made in a state with typically high humidity going to a state with very low humidity causing the wood to shrink more and split. It can also work the other way around though less often.
