500grains; I can respect a difference of opinion. I left my finger prints on every fine gun at that show. My factory CZ stock is nice too. I did strip the factory finish and found some nice grained wood underneath. Have bedded it and reinforced it with machine screws and agraglass. Installed a pachmyar flush fit forward sling swivel. Still have to put a lot of epoxy into the interior inletting to fill up the air space and put an oil finish on the stock. What I really like about the Brockman stock is the really snug, tight fit on the interior inletting... no air space to fill and recoil flexing to deal with. Also the two cross bolts are a nice touch. The factory finish on the CZ stock contains some red coloration on the seal coat and I prefered to strip it and see the natural wood color. Anway, two stocks can't be all that bad
