I have a Ruger M 77 in 22-250 that shoots groups of 2" - 3" with factory ammo at 100 yds. Since I can throw bullets that accurately I need to do some work on it. I plan to pillar bed this rifle first then bed the action. My question, can I make my own pillars out of brass? I am thinking that the brass might be too soft to do a good job. Should I go ahead and spend the $14 and get some aluminum pillars from Brownells?
