heres the thing. in doesn't mater if ones field points hit differently than their broad heads. why? because the thing should be set up for the hunting arrow not the practice arrow. as long as all the hunting arrows hit in the same place you're good to go.I just switched over to broadheads from field points and increased the poundage from 60lbs to 70lbs with my new bow and will lay to rest any logical reason that I may have had to use expandable broadheads. At 60lbs or 70lbs. shooting field tips or fixed blade broadheads there is no difference in the point of impact from 10' out to 25 yds.
