My groups are really good, touching at 20 and 30 yards, around a 3 inch group out to 60 yards. I can shoot a group, pull my arrows and shoot again and this time the group is still tight but about 3 inches lower, it bounces back and forth, one time dead on, the next time low. I'm shooting a Bowtech Allegiance, Drop Zone Rest, ACC 371arrows. Is it me or the equipment?

It's you, your dropping your bow arm, creeping, or anchoring different......it happens to all of us.

Rob/Pa is right. It sounds like your dropping your arm. It usually happens to me when I get tired.

From what your saying, I would think you do not have a stable anchor point. Sounds like your (unknowingly) slightly changing it each time which would lead you to shoot groups in different spots. Hard to determine without watching you shoot. It would be best to have someone watch you and see if they can spot the problem. Hope this helps!

I would agree wit the others...how do you anchor??

I usually just put my thumb into my cheekbone
