I've got two local dealers trying to procure a LH Savage barreled action in .22-250. Once I get it I want to have the barrel fluted and add a decent, after market vertical grip stock to the action. But I can't find it. I just called Stocky's and asked them if Bell and Carlson made the Tactical Medalist A2 in LH. She told me that they did not, but some guys buy the RH and mill out for the bolt on the left side and then fill in the relief on the right side. If this is my only option what material would I fill in the right side with?
