I just bought some Nockturnal nocks and some Rage 2 blade mechanicals for Turkey hunting this spring. I am trying to make sure my bow is all dialed in before it's time for action. My question is that I put the Nockturnal nocks in 1 of my arrows. . . my best shooting arrow. The others i left them how i had them for target shooting and i think that the arrows are falling a little bit lower before they were dead on. So what is my next step how do I get it back to shooting tight groups. I am new to archery so this may be a stupid question. But a wise man once said "You didn't know how to wipe your ass until somebody showed ya." So throw me a bone.

Thanks for the help

PS. The Nockturnals weigh 21 grams, The regular Eastons nocks that were on before weigh 13 grams.
