Broadheads not grouping
Hello,
I have an old Bear Kodiak compound. I can shot field points just fine and want to do some deer hunting with this bow. I have a set of 3 blade fixed broadheads and four blade broadheads. The three blades seem to group amuch better than the 4 blade, but I am still getting a groupof 8 inches at 20 yards for the 3 blade broadheads. Currently I group about 3 inches with field points (I know I need to pracice more). Anyway, my bow does has the old stick on arrow rest so I cannot increase plunger stenght. So without buying a new arrow rest I don't know if my bow is tunable. I am thinking of going to a mechanical broadhead. I know my penetration will not be as good, but I hunt in FL and our deer are smaller. Now if a big hog comes out I might regret it, but if I cannot accurate place the arrow penetraton does no good. Any recommends? Should I get a new arrow rest? Or mechanical broadheads? Or something else? Any help would be greatly appreciated.
Thanks,
Chris
