Mine is a 30-06, it likes Hornady 165gr SST, 51.0gr H414, 3.210" COL, light crimp, 2,600 fps.
With a cool barrel it will shoots less than 1" 3 shot groups @ 100 yards.
I too bought a R1 this year, i reload and it took many trips to the range before I finally found a recipe that it liked. It varied from 4" groups to less than 1" at 100 yards.
Keep trying.....
I just purchased a slightly used R1 in 30-06 with the camo stock, the gun shoots and functions great.
Can anyone tell me about maintaining the gas operating system?
