Stock breakage

[Cold Spring]

The OP's question was about the use of heavy loads and recoil effect on Parker stocks.

Those crude cross bolts and cracks pictured by Drew in the middle of the boxlock stock heads (Parker, Fox) may well be attributed to lateral pressure on the side of the stock, as in falling while hunting. Cracks in LC Smith sidelock stock heads are irrelevant to this discussion. Why post them?

On the other hand chipped-out areas on the sides of boxlock stock heads can be an indication of recoil effect from shooting. Can we see any pics of those on Parkers in particular?

Alfred: shotgun barrels have no moving parts, though there is some flexion with the shot and expansion with the ejecta.
Properly designed and fabricated barrels, using metal appropriate for the application, subjected to pressures for which they were designed, do not weaken over time...well, maybe in a few thousand years
The problem of course is corrosion, pitting, obstruction, and using shells for which the barrels were not designed. None of us can know the abuse our barrels may have experienced before we acquired the gun; but a bore gauge, bore scope and wall thickness gauge and help.

Frank: how can you know that a boxlock stock head split down the middle wasn't caused by excessive recoil?





THIS certainly looks to be from trauma

Nothing is for certain when it comes to recoil, wood grain structure, fineness of the heading, etc. but methinks the most common cause of stock head/middle splits on boxlocks is lateral leverage caused by a fall or some other sideways pressure.
