I'm with p_ham, sounds like you've got a picky eater on your hands. I have two rifles, both Savages, one in .308 and a 7mm Rem Mag. I've yet to find a production ammo that the .308 won't shoot within 1.5 MOA, and will shoot .5 MOA with my handloads. The 7mmRM on the other hand shoots lights out with my handloads (which took a lot of time and effort to find) and every off the shelf ammo I've tried get's a "meh" at best.
You've definitely found an accuracy node with your handloads. 2700 fps will absolutely get the job done, but is there room under the max load to hit another accuracy node? All other things being equal (accuracy and safety wise), I'll take more speed personally. If you can safely get more, then get more. If not, then you've still got a good shooting rifle that will do the job.
