Either Bullseye or Unique. Unique and Universal are TOTALLY different animals. In some instances, Unique will still be burning at the muzzle of a 16" barrel. Universal generally gives similar velocities per charge weight, but does so with a completely different burn curve. This is also why Universal has the reputation of burning much more cleanly than Unique. Universal will be @ 100% burn in a few inches, while Unique is still flaming on down the bore. I much prefer Unique for rifle loads over Universal, generally because it has proven over and over to have the accuracy edge. BE burns like Unique, very long and cool compared to similar "fast" powders like Titegroup, 231, and Red Dot.
You may also find the best accuracy below the trans-sonic zone, like in the 1050 fps area. If you crowd the sound barrier, best to just go past it by 1-200 fps to make sure your bullet stays supersonic all the way to the target and avoids transonic buffeting.
