Here is what I would do in your situation: Number each of your arrows so you know which ones are consistently flying astray. I use a permanent felt tip marker to mark numbers (or pips) on a vane. If certain arrows are not consistently grouping with the others, you can identify them easily and can determine if you have an equipment problem. If there is no pattern as to which arrows are out of the group, then it is probably a shooting form problem.

Check for vane contact with the rest. 90% of my grouping problems have been due to rest clearance problems. I use spray on foot powder for this. A group of new arrows may not have all their nocks 'indexed' exactly the same so check for nock alignment.

You may have a few arrows in your batch that may never group with the others due to differences in spine or straightness.
