I have never bedded a recoil lug or any part of the action, but I have been told it's easy to do55g sierra SBT 1365, 37.5g varget, lapua or Winchester brass, cci 200, br2, or fed 210M. That load has shot extremely well in several factory and custom 22-250s I've owned or worked up loads for. Work up to that load, free float your barrel and i highly recommend bedding the recoil lug or pillar and fully stress free bed it. Also make sure your glass is good. It should shoot itty bitty bug holes. Also if that gun hasn't been shot up till a couple weeks ago make sure the inside of the barrel doesn't have any build up of old sticky oil. Brush the barrel out to make sure you get it all out of you haven't done already.
