I have a new Hoyt Katera with a whisker biscuit rest. I have had the rig for a couple of months now and have shot it several hundred times. I am having alot of trouble with consistency.I can shoot 3 arrows and group perfectly and the 4th will be off 5 or six inches. I can have a shooting session in the yard and be doing well with it and the next day it is off. I have moved my sites countless times trying to get it right. I know it ain't the bow and it must be me. I know whisker biscuits are great hunting rests but are not really considered the most repeatably accurate rests available. I believe it is between the rest and lack of an anchor point that I use every time. I feel like I line up at the same point each shot but probably don't. My peep site is a true glow with rubber tubing- should I get a smaller peep? What is out there that I can use for an "anchor point"? I am planning on changing my rest also. I know this is not a target bow but it should do 3 or 4" groups at 30 yards if I do my part. Suggestions? Thanks in advance.
