I'm not sure why it wasn't happening before, but your current results are just about what I would expect when shooting 125g. field pts. and 100 gr. broadheads. 100 gr. field points should shoot higher too. Sounds like your nock pt. may have moved down, or your rest is higher for some reason. BUT, if the 125 gr. Tricks and T-heads are both shooting right with your 125 field pts. out to 30 yds. and beyond, there are quite a few guys who would like to have that problem.
