My next Gradous build will be starting shortly. We are just waiting on the Kreiger barrel to arrive within the next couple of weeks. My A5, Bender scope, Sphur rings etc. are all at his shop. After a lot of hard work by Robert (the best there is) we decided that the 6br is just not reliable enough to build as a repeater. So I have a 6mm barrel on the way with a 1:8 twist that I want to keep at 22" or 23". My options for the most accurate alternative caliber either a 6XC, 243. Not sure what else that would work for 100, 300 and 600 yard shooting. From my good Sniper Hide friend 95LTZ and Robert said there is no question but to go with with the 6XC because of its accuaracy. Looks like this is what I am going with. Just curious what other members think of this caliber.Thanks for your help and comments.
