At 64.5 I was getting a slightly sticky bolt retraction and at 65.0 some extractor marks.

Re: velocity?

Last year I started getting 50fps fast readings on my previously shot loads. A screw holding one eye was slightly loose. It could only wiggle about 1/16th and it was enough to matter. Check your settup plumb square , level and fasteners.
