Sorry to drift off topic a little here but this could be relevan. Mark what are you using for a cleaner for break in?
I use to see the 2~3 shots to settle one in after cleaning. But since I have been using BoreTech CU+2 I don't see this. I will not say this is a proven deal, but I have tested this a few times. My first shot after cleaning has been 1/2 moa to point of aim even when tested at 1000 and 1400 yards. I decided to try this after reading on the bottle you can leave CU+2 in the bore as a storage protectant. Then simply patch dry and shoot. It has worked for me even after setting a week in the safe. Patched dry and first shot was in the 7" circle on my target at 1400... Well 1395 to be exact.
