I do had bought a weatherby accumark it is an older gun chambered 30-378. I had Christensen arms stick a new barrel on it brake and action all done with trigger. Shoots 1/2 inch with factory 180 BT and right after I shot 8 of those I gave just a few swipe to the barrel and shot 180 accubond that were under 3/4. no complaining there, But I'm been kick around to get a new rifle. I look at the 1800-2800 price tag of these rifles with factory barrels. and i say thats a lot of money not to have accruacy garuntee. I know my 300 win mag browning shoots 1/2 or less all day long and that rifle cost me $750. I know you can get more repetive accurate shot out of carbon barrels but most people are not taken 20 odd fast shots and game especilly dangerouse game, you'll be eaten or mulled before you chamber the round. Sako,Weatherby have a garuntee. It is going to be tuff Steer towards the extreme or hunter for me, But I do like my carbon barreled accumark with the S&B scope. Most people say action is the heart of the accuracy I feel its the trigger
