This is my gf's first year hunting, I got her G5 Montecs. She is shooting a Parker Sidekick at 40lbs. My question is...I picked up her bow tonight up tonight and checked how the broadheads grouped at 10 yds in the basement compared to the field points. The G5's seemed to be an inch low of the field points. I realize the longest shot should be 20 yds. My question is should I mess with the arrow rest and try to get it dead on, or is it not enough to worry about?
