I'm looking for a tighter and more consistsnt shot. Currently my field point shoot perfectly but my broadheads are way off. I looked at tuning the arrow rest.
I'm shooting Muzzy four bladed broadheads and I was wondering to what extent should I worry about getting one or two of the blades somewhat indexed to my (3) vains. Should I get helical vains, scrap the Muzzys and get three bladed ones...
Helical fletching can help assuming your not shoot through a whisker biscuit. Have you shot your bow through paper? Is your Arrow spine matched to draw weight? I am by no means an expert on the topic but the little bit of shooting that I do I quickly realized that when broad heads are not grouping well or are flying erratically it was caused by me or the tuning of my bow. In my personal experience when I couldn't get my broad heads to fly nicely, shooting through paper showed me a couple things. One being that my arrow wasn't leaving my bow nice a level and two I was gripping my bow too hard and torqueing it slightly to the side.
Also where are you located? If you are anywhere near Red Deer go to Red Deer archery and talk to Pat. They helped me a lot there and corrected me of more than one bad habit.
I couldn't get muzzys to fly with the field points either.. my bow is tuned perfectly so I switched to the 3 blade shuttle t black ops and they fly dead on out to 40yds..
other suggestions are steelforce phatheads, rage hypodermics, NAP killzones, magnus buzzcuts all fly dead on with the field points out to 40yds
I am shooting Easton hex 330's with the 50gr brass insert and 2"blazer vanes
Glad the NAP's shoot well for you. Probably not Thunderheads??
I shot muzzy MX4's for several years. They were one of the few fixed blades broadheads that I found did fly pretty much the same as POI as field points. Very low profile. It does not matter that much about indexing. I still do it, but if my bow is tuned I find it makes little difference at distances under 50 yards.
I switched to montecs..have to re-sight from fieldpoints, but they group very tight. I wanted a cutting tip broadhead when I made a big drop in draw weight.
Most likely tuning issue or arrow spine, some bow can be tricky to tune. Also contact a good archery shop, shooting technique flaws will affect arrow flight. bow torque effect will be amplified by the broadhead. If running out of time you can hide some of your issues by shooting a good mechanical broadhead but fixing the problem would be better.
