Shot several decent groups at OAL of 2.625 and worked up from there. I also played around with the powder charge of IMR4064. Worked all the way up to 42.3 Gr, which is .8gr higher than the highest Max charge in any of my loading manuals with no pressure signs. I settled on 42gr and the OAL of 2.625. I worked seating depth up to 2.700 with okay groups, just seemed to like the deeper seating depth the most. I have shot enough groups with that combination to feel like it is accurate enough for what I will use the gun for.

I am fixin to start coyote hunting and it should do the trick!

Anyone chronographed 4064 with bullets around 70gr?
