I don't have a Encore in 30/06. I do have one in .308, .270, .223, 22-250, 209x50 M/L, .243, .300 win mag, in rifle barrels. I also have a .308 win 15" handgun barrel and a contender in .35 rem. I may like it just a bit to much. Every one of these barrels will print a 1" (5) shot group at a 100 yards from a bench. I guess the 30/06 will do the same.
