Bad load? Bad scope? Bad barrel

[Phil Rizzo]

What are you going to try different than previous efforts?

Keep it coming. The CEB bullets have a driving band on them. that band is 0.025" off the lands. It is as good of a point as any. Varying powder charge in my last OCW iteration gave me 2 groups of about 1.5", one group at 2" and one group at 2.7". I need to quit posting and load more rounds to test!

I see you have realised the rifle has fallen out of the node.
I alter powder charge to get back into the same previous good grouping velocity, I do not chase the lands as the throat erodes, this can, and does, change harmonics for the worse, not the better.
It will be obvious if you get into a node again, even if the throat is on its way out. Often using heavy long bullets helps the barrel shoot good (MoA+) for quite a bit longer.

Cheers.

Please don't abuse me. . .it was bad! This is from last Sunday.

And yes, there is a round that I'm not sure where it is from. . .I could be off and some of the groups under 2" are really over 2". . .Dang!

Change scope.

Were you ever using a Lead sled during you sight in tests?????

No, but that reminds me I need to put that thing on Facebook marketplace who the hell wants a lead sled in their garage anyways!
