I shoot a high country brute force 73 lb pull 28.5 inch goldtip 7595 with 5 inch helical vanes.the broadheads are thunderheads and rocky mountain iron heads both 100 gr neither one will group close to my field points .they group about 2 inches to the right at 20 yds and about 6 inches to the right at 40 yds i know this is acting as a weak spine but the 7595 is a plenty enough stiff shaft.I have moved my arrow rest to the left and it helped a little but it made my field points hit to the left a little more.i have lowered my draw weight but it did not seem to help.My bow has been properly paper tuned.I just wonder if anyone else has any suggestions to fix this problem.I am interested in any names of some good fixed blade broadheads that fly like field points.
