I used powdered tungsten in one stock. I drilled holes with Forstner bits and poured in powdered tungsten and capped it off with a 1/4 layer of epoxy. I added 16oz. total using the butt and pistol grip areas. Tungsten has the highest density of the readily available metals....unless you have access to a military range.
Yes....definitely more $ than lead.Ok I checked the price for tungsten. Lead is looking better.
Lead shot and epoxy resin, like acraglass. Mix the resin, then add shot. Pour the mix into the stock.
That's how I do itGo with a fine shot mix some epoxy (clear infilled) and make a slurry just coating the shot. Stuff it in the cavity. When you have the weight you want, pour a barrier of epoxy in top of the cured shot/epoxy mix.
