I ran the 135s for a bit, still running the 110s in wife's 6mm. Also tested the 153s. They shoot, but the difference is minimal between them and running a Berger BT or Hybrid. Not worth the extra $ in my opinion. Biggest gain was in 6mm running the 110 at 3100fps, gained 7min at a mile, the rest were only 2-3 min. At an extra $20-$25 per 100, no thanks.
