tuning problem

I request your help, please. I purchsed a Mathews Switchback XT two years ago as my first bow. Haven't harvested anything, yet, but I enjoy shooting. Well, as I've gotten better, I'm taking notice of so many things. The other day, shooting from 30 yards out, I was hitting the bulleye pretty consistent, but I noticed that my arrows looked to be falling/angling to the right. Not sure what this means. Anyway, I started to think that maybe the bow wasn't tuned. I took it into Cabela's and spent about an hour with the bow tech. Unfortunately, we couldn't tune the bow. The results were inconsistent. Sometimes I'd get a good shot while others fell to the left. We moved the rest to the left three times and results were still inconsistent.

I'm using a Schaffer drop-away rest, MAT-1 for Mathews bows. Would appreciate any information you might be able to offer. According to the tech he thinks that the fletching might be hitting the bow. We both looked down the shaft and it seems that he could be right.

Thank you for your time.

I would paper tune it. My arrows at one time looked the same way in my block target. After I paper tuned it they were all straight in.

As far as your arrows, make sure everything on them is the same, same arrows, same fletchings, same size and weight tips, same nocks. Are the arrows made for that weight bow? Also, what fletchings are on there? Are you shooting a release? Is your form the same? So many variables.

I would find a Mathew's dealer near you and have them look at it. Cabela's does not sell Mathews.

To check if it is indeed fletching contact with the rest or bow...get some spray footpowder and spray it on your fletching. After you shoot, check the fletching for 'crease' marks in the powder. If they're there, adjust the nock to clear it (rest) or the center shot of the rest if on the bow.

Simply looking down the arrow shaft will give you a good starting point, but an arrow, at release, goes through some significant gyrations, and that may be what is causing contact.

Is the spine of your shafts matched to your bow? It could also be that they are too stiff. If you matched the spine to your bow weight, you can step up the point weight (100 gr. to 125 gr.) and see if that helps.

...but my instincts tell me, that as a new shooter, you are probably dropping the bow at release...trying to peek at where the arrow is hitting. Focus on holding the bow steady until well after the arrow is gone. The tests I mentioned above can be adversely effected if your form isn't right...so work on holding the bow, first.

I would take the bow to your local Mathews dealer rather than Cabela's.

I would start from scratch. Have the bow's spec put back in place. You'd be surprised how far off the bow can be when not in spec. Make sure your arrows are spined correctly. Make sure that you aren't torquing the grip of the bow, that will effect the shot as well.

How many shots have you put on the bow so far? The Zebra Barracuda that first came out with the Switchback in 2005 did have some stretching problems. Mine stayed in spec for about 1000 shots. After the first 1000 shots, the axle-to-axle would be off by almost 1/4" after 25-50 shots. Once you get the bow tuned, I would check the axle-to-axle and brace height measurements often. If they continue to be off, you might want to look at a different string.

I have a Schaffer MAT-1 on my Switchback. Once you get that bow tuned and shooting well, you'll really like that rest. ;)

Thanks to all. I'm going to take it in to the local shop next week. It's the only way to make sure everything is going to be ok.

I did move things around this morning, regarding my bow, and I'm back to hitting the bullseye. Unfortunately, I'm not confident that all is well, therefore, I'm going to let the professionals handle this one.

Good luck to all this season!

I took a piece of spider wire fishing line and taped it to the top of my limb on my xt ran it threw the pocket were the cams are located the string should go in the notch comes down to a v run it all the way length of the bow threw bottom just like top and pull it tight line your rest up in the dead middle of the string worked great for me
