[QUOTE="TexasHunter, post: 465091, member: 26082"] A couple of thoughts that haven't been mentioned. (1) Try a couple of benchrest brass prep tricks like deburring your flash holes and uniforming your primer pockets. I found this to make a fairly significant difference in cheap brass. (2) Instead of (1) buy a box of Lapua brass and try that. It doesn't need any prep. (3) You may have done this, but if not, set the COL to touch the lands and then vary the powder drop until you get a one hole group. (4) Make sure you are not oversizing the shoulder. Even though the case headspaces on the belt, you don't want to push the shoulder back more than .001. (5) Have you checked the runout on your loaded rounds? (6) What type of barrel and how many rounds? (7) What's your cleaning regimen? Hope this helps Dale [/QUOTE]
