Put a new barrel on my 30-06 model 700. I have always only "neck sized" my brass, and the old brass didn't fit the new barrel (no surprise here). I "full case" sized the brass, and all is fine. Worked up some loads and went to the range. I have 3 of 6 combos that are already sub-MOA! I'm thinking I love my new barrel! But when I made up the next set of test rounds (neck sized only), they will not chamber? This is the same brass that was fired from this barrel? They were a little tight to eject, but not to the point that I was at all concerned. I guess my question is this; can this be saved (short of gun-smithing heroics), or should I just go ahead and have the thing chambered to a 300? Should the gunsmith that fit my barrel Fess up here, or is his obligations done (it does shoot spec ammo)? Anyone know a GOOD gunsmith in the Savannah Area? I really wasn't expecting to spend more money on this thing!
