I shoot expandables and I have been hunting with them all year and havn't taken a shot over 30 yards yet.I was shooting my Block yesterday and at 10 yards I was right on. at 20 yards i was hitting about 3 inches left and at 40 yards I was hitting about 6-8 inches left. My question is since my misses are increasingly farther away from bullseye the longer my distance is does that mean that my rest may have been knocked out of wack. Also I use a simple 2 prong rest and the little rubber boots on the tips are starting to wear down. If one is wearing more then the other would that also have an effect?

Anybody have any ideas?

Thanks
