[QUOTE="Mike in Texas, post: 73895, member: 1889"] Pac Nor did a pair of 308's for me recently. 1 barrel is absolute min spec with a .337 neck. Very tight. the other barrel is nothing more than a factory remington chamber they call their "sniper" reamer. Max dimension with a long throat. There is no accuracy difference in the barrels at close or far distance. The loose chamber is alot more user friendly. Both barrels shoot in the very low 0.2 range for 5 shot groups. I'd go big and save the hassle. A concentric chamber of any dimension is a huge improvement over a factory cut chamber. [/QUOTE]
