Thread: Diagnosing a accuracy problem with my .222

It may be worth a try doesn't cost anything I had a rifle that I thought I was doing the right thing by floating the barrel fukn thing shot like shit after I did that

Is the nice group the first few shots and then it walks around? Or just a few of the spread happen to end up close together but not any particular timing?

Find a decent gunsmith in your area, with borescope, and get him to give it a going over. Throat, general barrel, crown area. Mitch Maxberry? At this stage you don't have enough info to make a decision on a countermeasure. You are not yet at the chopping bits of stage.
(Lots of people now have borescopes but that doesn't necessarily mean they know how to interpret what they see.)

As already posted by someone else, a cleaning rod with patch will usually momentarily "go easy" as it passes thru a bulge. A bulge doesn't always kill accuracy. Probably a bit more concerning in a centrefire but I have seen lots of 22s with bulges that still shoot bloody well. (Got an old Sako P54 exactly like that.) You can also usually see a bulge. Sometimes quite distinctly, sometimes just a discoloration in the blueing.

My original 22-250 eventually grouped like yours. Few shots good then sprayed. When I finally re-did a seating depth check the throat was so far advanced the if I tried to seat a projectile anywhere near the lands, the projectile wasn't engaged in the case neck. I wouldn't expect a 222 to burn out like that though.
