Bought a premium auto body fibreglass kit from Canadian Tire, mixed and poured it into the butt end of a Tikka Varmint rifle including the fiberglass cloth and a couple lengths of threaded rod for good measure. Generated some heat on curing but the electrical tape wrapped around the pistol grip cap kept it from coming out. Added stiffness and weight, maybe 2lbs total. Better balance, controllability, and accuracy and no problems since done 7 years ago.
