My D loop was wearing out so the local shop replaced it. My groups are now about 4 inches low so I have some questions... Is this normal? Should I focus on shifting my rest or sight to correct this problem? Thanks, Tom
Probably just your rest, you may want to think about looking to see if your arrow and nocking point are straight.
If you didn't move your rest, move the loop. Twist it around the serving to move it down like a nut until it is hitting back on.
If you are shooting low your knock point was moved up. Before you move your sight I would shoot through paper and see if your hole is perfect or not. Because who ever put your knock on may have actually straightened your arrow out with out saying anything or they may have made the mistake of moving your knock with out noticing
You don't want to do that. It will twist the center serving. This is another reason I serve nocksets in. I can change the loop and not lose my tune. What has happened is the loop is slightly higher than before. A slight rest adjustment should fix the problem. Sent from my SAMSUNG-SGH-I317 using Tapatalk 2
You don't want to move the rest to much and have it not in the center of the string or very, very close. If a string is served tight enough, it will not move the serving at all. I do it on all mine and have since my shop owner taught me to do it. Did I mention he was ranked 7th in the world at one point during his pro 3D career? I have only had it mess with my serving once and that was with this new Prime string that was separating before we re-served it by the way. Since the center serving has been re-served, I have moved it several times to fine tune the bow and it is just the same as new. If its to tight to move it, take it back to the shop and tell them what it is doing. I feel sure they will be able to fix it and watch them do it. Pay attention and learn all you can while they are doing stuff and ask questions also. That's how you learn.
Center serving is touchy. Too tight and it causes constant settling, too loose and it is separating. Gotta be careful to not get it too tight. I have learned from one of the best as well. His students have set world records with bows he has tuned.:D that with 30+ years experience. If your trying to move it to adjust 4"of impact difference, then that will take a full turn or more and that isn't acceptable. I would completely retune but this time it would have tied in nocksets.

I've done it plenty of times and haven had negative effects is what I was trying to get at. If the shop would have done it correctly to begin with and squared it ( maybe they did and it was out of whack to begin with ) he wouldn't be having this issue. So technically without having the bow in front of either of us, we may be steering him wrong anyways. It could be that neither needs adjusting and it could be this sight is off now due to it being set up properly if it wasn't before.
True, thats why I said I would start over. It doesn't take much though to make a 4" poi change. Sent from my SAMSUNG-SGH-I317 using Tapatalk 2
This x10. Take the bow back, re-square, get center shot, shoot through paper, and begin final tuning. I like my D-loops tight enough that they will not slide around the string. I like my stuff not to move.
I like to put a brass nocking point just under the top knot of my D loops and above my nock that way if I have to change the loop I know right where the top knot should be tied.
I wish you were in CT so I could go to you with my bow problems. I haven't had any yet this year (knock on wood...I think I'm in for a long season) but you're way more thorough than any bow shop around here.
