rabbiter Posted April 18, 2014 Report Share Posted April 18, 2014 hi guys,i took my new a bolt out today with my hmr to zero them,got the hmr bang on at 50 yards,then out to 100,no problems,then did the same with the a bolt,1" group at 50 yds,then at 100 yds it wasnt grouping at all,tightest was about 4",its a .223,using winchester varmint x 55grain,the mod is an atec cmm4,any ideas what might be wrong?...........DAZ Quote Link to comment Share on other sites More sharing options...
rangey Posted April 18, 2014 Report Share Posted April 18, 2014 try a few different rounds.tried about 8 different types and weights in my howa 223 and nothing would come near hornady 53 gn superformance in mine so i stick to these.plus if its a new rifle the groups usually get tighter as you put a few more rounds through it and get use to shooting it...

Dougy Posted April 18, 2014 Report Share Posted April 18, 2014 Start with basics, scope mounts tight ? stock screws tight ? shoot with mod off ? Eliminate those issue's first, trust me loose mounts are a common cause. After that try different ammo, Quote Link to comment Share on other sites More sharing options...

kent Posted April 18, 2014 Report Share Posted April 18, 2014 Something is likely amiss with it like said take the mod off and check all action screws, mounts etc. Put some good ammo through it then take it back were you bought it. My bet its the moderator or screw cutting (have a magnified look at the crown some fools ram a revolving centre hard in and mess it up when threading) Quote Link to comment Share on other sites More sharing options...

kent Posted April 18, 2014 Report Share Posted April 18, 2014 A gun that has not been leaned really well will not run 4 moa at 100 yards because of it as much as I like a clean bore that's just crazy. It wont help though but if you get an extra inch out of it I should be surprised. Quote Link to comment Share on other sites More sharing options...
kent Posted April 18, 2014 Report Share Posted April 18, 2014 warne mounts (new) nikon m223 scope(s/hand)........ Second hand scopes can be duff, if taking the mod off and checking screws, mounts swap the scope out for a proven one. Some toe rags sell their broken junk rather than fix or bin it! I take it the gun is new? Quote Link to comment Share on other sites More sharing options...
