the main problem in trying to accurately diagnose, the most likely source of most problems, posted on the internet forums.
is that your totally dependent on info ,you can,t personally verify and a great deal of the info you need,
is either not specified nor is most of it, accurate.
I've repeatedly found a great deal of the problems posted are the result of both improper component parts like scope mounts, or rings,
installation and a failure of the guys posting to even understand fully the questions asked.
I've had lots of the local guys having problems resolved with a careful dis-assembly, cleaning and careful re-assembly.
loose scope mounts, defective scopes, loose or overly tight action screws badly bedded rifles, and badly fouled bores are common.

Thanks for all the ideas. I checked the crown and it looks good to me, but i'm going to get it checked out again. I'm sure the gunsmith checked already but i"m not sure. I think they should have. Someone said that the forearm nut could be too tight or not torqued correctly could make the grouping bad. Where would that torque nut be located at? I looked it up and I have seen other people have this problem but no one said where it is located. Looks like another trip to the gunsmith.

What rifle are we talking about? Is this a BAR? A pump, a bolt? I may have missed it, but I don't think I saw anywhere that said specifically.
