Dan- what part of AZ are you in?? the sendero is a great rifle. is yours new? a lot of the factory triggers can be real good. i shot federal factory 180 tsx , i got it free, into .18" . however i do not use barnes bullets. my 300 sendero had a vais and a jewell trigger. the vais was more important of those two. i shot 210 berger handloads. i never shot any other factory ammo. for accuracy, a load with a berger bullet for sure. HSM and others load them. also i do not use matchkings for hunting but they are accurate. fed gold medal match and other match ammo should be accurate. i deleted some stuff on CW too thanks. enjoy. ron
