Ok I am finally getting to the point I can finish my PRS bolt rifle build. I have an MDT ACC chassis. Using a Terminus Zeus QC action and will probably get a barrel from Josh at patriot Valley Arms. I intend to go to 6mm GT. What should I look for as optimal barrel length? Probably going to go with an M24 barrel profile. Or should I just go with a 24" 6.5 Creedmore barrel until I finish my reloading set up in a few months?
