It worked! I followed the Benelli gunsmiths advice and it worked perfectly. Only let the red loctite cure for about 6 hours but it was enough. Apparently the stock bolt was set in the recoil tube spring cap by blue loctite. Didn’t know that blue loctite was strong enough to require breaking the bond that strongly. Anyway, after finally removing the stock bolt from the recoil spring cap, I just loosened the red loctite by placing the end of the recoil tube over my stove burner for about 7 minutes. That was enough heat to break the loctite and allow me to unscrew the recoil tube spring cap from the recoil tube. After that I needed to scrape the residual red loctite from the threads of the recoil tube and brush out with a bronze barrel brush. With all the parts finally out and brushed and wiped clean, I now applied Vibratite to both the stock bolt and recoil spring cap and let dry for the recommended 30 minutes. Then reassembled everything. Hope that this will be a good fix and that my stock (walnut aftermarket) won’t come loose after shooting 50-100 shells of high brass buck or slugs. What an ordeal! Thanks again to the Benelli gunsmiths!
