any decent gunsmith can install a stock re-enforcing cross bolt behind the recoil lug in the receiver
if you feel better, I know I did it on my and Jacks browning A-bolts rifles in 375 H&H browning A-bolt,
I simply measured very accurately , drilled the required hole and recessed the area where the bolt heads would be.
test fitted the cross bolt and used lots of bedding compound
once installed a bit of bedding compound and paint on the synthetic stock and theres zero visual indication its been installed,
but the stocks significantly stronger, I installed a cross bolt behind the recoil lug and behind the rear action screw,
once installed and covered with bedding compound and the stocks repainted you have no visual indication either was ever installed.
