Has anyone ever used quiksteel to fill the factory synthetic stock forearm? I've debated getting a boyds varmint thumb hole stock for my heavy barrel 308, but I figured I would try a cheap alternative first. The stock flexes in my hand, let alone on the bipod. I figured the quiksteel would solidify the stock enough to do the shooting I'm doing. If this won't work I'll just spend the $150, but for the limited shooting I do, cheap would be my preferred route.
