I was just wondering if anyone else has had problems with the G5 Montec broadheads chipping or breaking while shooting into target. I really like the way they look, but not getting good results. 2 already have chipped blades from hitting other arrows in target and I cant get them to group to great. Also been shooting ThunderHead 100's and they seam to hit closer to where field points hit, but every third or forth shot with them I get a flyer that will be way off. Any suggestions.
