Am about to try and build a super accurate rifle. I just bought a Remington 700 short action that was originally a 243, want to have the action trued etc. Also want a 28" heavy SS barrel. I need advise on what caliber would be suited to this action (Bolt Face)? I can order a stock from Richardsons or you may suggest a company to me The rifle will be used for Deer long range from a rest as well as some target work. Will be most grateful LOU
