OK Let's be the devil's advocate here. The original poster stated that he has been in archery for only 8 months. Now I on the other hand have been shooting a bow for about 55+ years. In the past decade I've purchased bows from different manfs. (Hoyt, Martin, Mathews) and different models of bows by the same manf. I set up my own bows and I'm pretty good at it. But I have found that until I get accustomed to a particular bow I can be shooting dead on at just about any range one day and be off a bit the next. It sometimes takes me about a week of shooting to get accustomed to it. And the culprit always seems to be a slight "feel" to the grip design.
One thing I don't do is paper tune. Some swear by it. But I don't. I set up my bow, then do walk back tuning followed by broadhead tuning. And do this only after I've been shooting the bow for a couple weeks. And without fail (except for original Muzzys) I can get my BHs to hit the same POI as my FT. For some reason the original Muzzys always shoot slightly left or right of my FTs. But they do so consistently. So all that would be needed would be a sight adjustment.
To prove this to myself I shot FTs, Magnus Stingers, Rage Hypodermics, Muzzy Phantoms, Slick Trick GrizTricks and ViperTricks and original 4 blade and 3 blade Muzzys all of 100 grains and the Muzzys were the only ones that were out of the POI range.
