I'll always choose accuracy over velocity, but there's often more than one accuracy node in load development. I've developed several loads in 6.5 CM, and the powder charge you've settled on is a bit lower than what most loaders use for this cartridge.
My loads in H4350 (which is a great stable powder for the 6.5 CM) are in the 41.8 range, delivering 140-143 grain bullets in the 2750 fps range. You didn't state what your velocity is, but with that powder charge, I'd guess in the mid 2600s. These loads of mine are grouping 3-shot groups below .5 moa, so I'm not giving up any accuracy.
Most powders are around 50 fps per grain, so you're leaving about 100 fps velocity on the table. That's not a ton of speed, but if you wanted to continue the load development, I'd bet a pastrami sandwich you'd find a good accurate load in the upper 41 grain range. It will give you better terminal energy and better wind compensation.
I'm shooting a CA Mesa with a 22" barrel, so I'm giving up about 20 fps with the shorter barrel too.
