BH tuning a Hoyt
[/align][hr]
All summer I was shooting Easton 2114 xx78 27” long at 56 to 58lbs I use a release with a trophy taker shaky hunter rest my draw is 29” the bow is a Hoyt ultra tech the arrows flew and grouped great. I had a bunch of 2117 xx 78 and xx75 28” long so I figured I'll use them for deer with the extra weight would aid in added K.E. well they fish tailed all over and grouped all over the place. I put the expandable broad head on the 2114 and they grouped perfectly. Are the 2117 over spined for this set up? Easton charts show as ok but i was told the charts are on the stiff and heavy side for liability reasons Any help is appreciated thanks mike[/align]
