.308 is a better caliber for distance shooting imo. Because in higher wind conditions the .308 will have a higher ballistic coefficient.
I have Custom .308 EBB and it's set up for long range shooting. It can bang a 16" gong and not miss at 540yards. It's also been taken out to 1000yards.
When shooting to dial the gun in, shoot at least 3, 10 shot groups. Mathematically a 10 shot group will open up a 5 shot group by 40%. This will give you much better data and eliminate the luck and give you real data on which bullet works best.
Good luck on your journey.
