Has anyone had this problem? If so what did you do about it?

snokid Posted March 17, 2004 Share Posted March 17, 2004 Do you have the set screw on the side tight? Bob Link to comment Share on other sites More sharing options...
steve223 Posted March 17, 2004 Author Share Posted March 17, 2004 Yes its tight Steve Link to comment Share on other sites More sharing options...
ErikW Posted March 17, 2004 Share Posted March 17, 2004 Any wide temperature variations? Rumor has it the C-More shifts POI as the plastic expands and contracts. Link to comment Share on other sites More sharing options...
steve223 Posted March 17, 2004 Author Share Posted March 17, 2004 Erik that could be the problem,The last week the temp. has been in the 30s in the morning to the high 70s or low 80s in the afternoon. Steve Link to comment Share on other sites More sharing options...
Loves2Shoot Posted March 17, 2004 Share Posted March 17, 2004 I've not seen problems like that with my c-more with wide temp variations, you might use some thread compound on your screws. Link to comment Share on other sites More sharing options...

DJPoLo Posted April 18, 2005 Share Posted April 18, 2005 I just encountered this problem with my Cmore. Off 8" high and 8" right. A week ago it was fine. Very frustrating. -Chet Link to comment Share on other sites More sharing options...
The Hangin' Chad Posted April 18, 2005 Share Posted April 18, 2005 The best fix I have seen for this is to buy an OKO. THC Link to comment Share on other sites More sharing options...
shred Posted April 18, 2005 Share Posted April 18, 2005 Also take a Sharpie marker and put a mark where your elevation & windage screws should be... makes it easy to see if it's the screw that moved (& easy to get back 'close'). Change your load and the mark comes off easily with bore cleaner. Link to comment Share on other sites More sharing options...
spd522 Posted April 19, 2005 Share Posted April 19, 2005 If anything, the CMore on my Open Para has kept a constant zero for years, as long as I don't change the load I am shooting. I have been very impressed with it, not to mention the long battery life. Link to comment Share on other sites More sharing options...
