I have been shooting 100 grain rocky mountain broadheads and decided to switch to 125 stinger broadheads now my arrows are shooting low is the higher grain causing the arrows to hit lower
well you did add 25 grains to the arrow setup are you consistently hitting low at all yards that you shoot? If so yes the 25 grains cause you to hit low.
It not only slowed your arrow down slightly, but it changed the bows tune with that broadhead/arrow combo. It's not a bad thing, but you will need to retune your bow with the heavier points.
Good point on the tuning issue as well. Just curious how much tuning/change will there be with an increase of 25 grains? What do you start with first? Do you move your sight cage or look at other items first? Just curious I guess.
