I don't really shoot any further than 40 to 45 yards. I can keep a 3 to 4" group on the first 5 or so arrows then I think its more me than the arrows or bow. My shoulder is not the greatest and I have a hard time holding still after shooting to many. My first couple are usually within 2" inches of each other and are where I'm aiming. The first one is the most important one to me as you "usually" don't get a second chance at a live animal. Would it be beneficial to go with a 125 grain instead of 100 grain tip??
