Hey RC,
We met at the range last weekend a couple of times. I had the the other Creedmoor there.
I am glad you found a load you like. I too am playing with the OAL. Test, test, test, right???
It is interesting that even though you lowered the load to 41.1gr that your velocities are still good. I am guessing this is because your longer OAL is putting you closer the lands, which increases pressure. You are getting great accuracy which is the key thing.
I hope to see you out there again soon.
