I like the 130's in my 6.5's used for PRS, with very good performance from the Berger 130 OTM Hybrids in my 6.5x47. 41.2gr of H4350 produces 2890FPS from my 26" Kreiger Med Palma barrel. Ballistics are very close to the 140's driven at 2750FPS to 1000+yards.
Your rifle barrel twist rate? (For 147 gr. and higher it should be 1:7).
Try 140 ge. ELD-M or 143 gr. ELD-X if you have not done so already. I get 1/2 MOA with Hornady 140 gr. ELD-M from my 1:8 twist Ruger Precision Rifle. Almost as good with 143 ELD-X Hornady factory loads.
