[QUOTE="bdpayne2000, post: 1002597, member: 59260"] So here is the deal Pacnor barrel, 180 VLD's, has shot lights out for about 250 rounds. Always less than MOA and when I was doing my part truly 1/2. Last time out it was not good from 600 yards. First group 9". Second group a little worse and the POI even shifted. Checked scope, base and action and everything is/was to spec. No wind as dispersion was verticle not horizontal. Weather was 50 degrees and have shot it in much warmer weather with much better results. My cleaning regime is BBS and then wipeout for copper. Barrel cleans super easy and is leaving virtually no copper. Could it be a carbon ring in the throat? I have Isso paste and brush but have not used it yet. Thanks Brian. [/QUOTE]
