So, here is where it stands today.

I went back to the range with a bore sighted Weaver K10 that is known to be good.

Had two loads. Both loads well below maximum. 52 gr. Speer match and either 38 or 38.4 gr. H380.

No good. Groups at least 4 inches at 25 yards. Put the NF scope back on and the results were essentially the same as last week.

Took the gun back to the gunsmith and asked him to go through the rifle to see if we can figure out what is wrong. The smith does notice some "frosting" at the throat that is not abnormal for 900 or so rounds.

I have 100 new brass that I am going to load the same as what I have been using and take another 22-250 to the range on Friday. I have an older Ruger M77V that has had less than 250 rounds fired through it since new. I am not sure what that will tell me but right now I am really puzzled. I just can't imagine what is going on with the gun.

I scrubbed the bore and the patches come out clean. There is no visible damage to the crown and the rifling looks good.

This is a real puzzle for me.

The pattern actually looks like a 22-250 shotgun. It is THAT bad.
