What’s a realistic number for 6.5prc velocity

My old 24" with elites was like 29 something. But with 156 I was at 3k.
Can't remember what powder I used for the elites. But the 156 was n570.

140 Berger I'm at 2943 with H1000. Just tested a couple weeks ago with Magnum and was at 2960. (wasn't enough to have me change over to Magnum until I'm maybe out of H1000) This was in a 22" barrel. I really want to see what Grand will do but I expect it'd be too slow for the bullet weight. It works for 156 Bergers as I was able to get 2860 and those hit pretty hard.
 
Don’t have a PRC, but my Tikka 6.5 CM with 135gr Bergers is hitting 2960 with RL26, starline brass, and no pressure signs at all. If you can get your hands on any RL26 I think you should be able to hit close to 3100 with 140’s.
