Hidden Stock Repair

With modern materials (allowing more strength even with weight limits), there is really no reason for stocks used from the bench to be so thin and narrow around/below the action. Guns that were carried and gripped by the hand were narrow for a reason. Now that purpose is gone for bench guns. I've discussed this with a few stockmakers. Most don't get it. A thicker, stronger, more robust action area might have multiple benefits.

We acquired one very handsome figured walnut/maple stock that had only half an inch of wood below my Stiller Viper action near the front. Sadly that laminated stock proved so flexy that it was basically a complete failure. The forearm would bounce into the barrel every 3rd or 4th shot, sending bullet impact out 3/4" at 100 yards.

Restocked in a beefier, deeper, stronger composite stock, the very same barreled action shot many 5-shot groups in the ones.

That pretty walnut/maple stock was made into a trophy. Good to look at, but useless in its intended role.

^ The recoil lug area sure creates a well that is a weak spot, because the stock is not yet widening toward the 3 inch for-end where this occurs. At the same time the action can’t readily be seated high in the stock because the trigger won’t protrude the correct amount. Flat trigger shoes that are adjustable can alleviate that problem.

On your stock Boss, I’d be tempted to affix by bonding and discretely bolting a shaped length of thick carbon fiber to the bottom of the stock. That bottom would be ultra smooth, attractive and inflexible. I’ll attach a picture of material that is available that is as or more rigid than titanium but prettier.

I was thinking the stock had a glued in action and it broke when removing.
@Greg Brooks will know better how to answer what happened.
He did a great job of repairing it with devcon.

It’s actually an IR 50/50 10.5lb rimfire stock. For one of Jerry Stiller’s 2500x series actions (Holeshot) - drops in for a 40x/700 inlet. Bolts into that specific stock but I might silicone it in there as well. Made for punching score bullseyes. The amount of flex/recoil converted to the stock itself is very minimal in this case. But there are multiple carbon fiber laminated layers in there as well to add extra support. The issue we deal with in rimfire specifically is vibration; from the firing pin/primer, charge detonation and to an extent tracking after the charge has been set off. Remember that little lead bullet is moving 3x slower than an average center fire copper bullet. Takes a while for it to leave the barrel. So any vibration or tracking has a larger influence - wood and laminated wood actually do a better job of absorbing these vibrations than fiberglass, straight carbon fiber etc.

That being said lol - I wish the stock maker gave me a little more meat in that specific area cause even with a slathering of release agent I busted that piece when pulling the action out after bedding.
