when my arrow falls off the rest it is during practice. i just bought this bow about a month ago. i can draw my bow sitting down it is just that unless i go so slow that i am barly pulling my bow back the arrow just falls off the rest. it usually falls at about 6 inches or less before i am at full draw. it is weird b/c all the sudden the arrow goes straight up and then 2 the right falling off the rest. i cant think why it is doing this.
