Been reading a lot about pillars lately. I've bedded all of my rifles and several for others using Brownells and now Marine Tex. On the last few I used the method shown in the Best of the West videos of overboring the screw holes and filling in with bedding compound. It essentially makes a 1/8"-3/16" thick pillar out of compound. Pretty simple to do and doesn't cost you any more than the basic bedding compound. I've seen the price of steel pillars and that could add up real quick. Is there any reason that metal pillars would be better than the compound?
