I disagree, Paul. The 168 A-Max has a much higher BC and can be safely driven about 500 fps faster than the 220 RN. Consequently, the wind deflection for the 220 at 600 yards is more than double what we'd get with the 168. Do the calculations and you'll see the difference. (To make matters worse, the 220 RN starting at 2000 fps goes transonic well before 600 yards - not good for stability.)
MJ - consider the Hornady 178 ELD, with a bit more bearing surface and BC than the 168. Might be safe with the same 38 gr. 4895 load, but please observe usual precautions when changing bullets. (Back off, work up.) IMR4350 probably a better choice.
