I installed my feather rest centered on the side plate, with about a toothpicks width between the rest and the side plate. The rest is also centered fore and aft on the shelf. The side plate is 0.057 inches thick and is smooth leather. With a felt on the shelf left/right was OK. Now, with the feather rest, the point of impact is 10 or so inches to the left from 15 yds. Tried cock feather in/out. No difference. Can I correct this? I like the feather rest, it looks good and it is silent. Pulled the feather rest off, put the felt back on and the arrows again went center.
