6.5 creedmoor with ARComp

Not in 65CM but have run a ladder with it in 6.5x47 with 123 custom comps.
Should be very close to what you are asking about.
Will probably be about 1/2 to 1 grain higher in the Creedmoor.

I saw zero pressure signs but of course start low and work your way up watching for any warning signs.
