My bow shoots 3 different broadheads in the same holes. 2 blade Magnus Stingers....3 blade Muzzy and 4 blade SteelForce. All 100 grain.
The SteelForce heads did not however fly as well as the other 2 to start. Still very good but not great. I then changed the alignment a little and BOOM....right with my other heads. No changes to the bow or arrows.
I don' t know for sure that it makes any difference but those little plastic rings only cost a dollar so why not just get them and do it?? It doesn' t hurt.....I know that much
