Tuning help

I am shooting a Diamond Rock at 62lbs. I am having a hell of a time getting my new xx78s to fly worth a darn. I have been practicing with xx75s in a 2315 this summer and shooting great. Down to 2 arrows so I bought a new dozen of the xx78s in 2312 because that is all they had and the guy at the shop said it would be similar.

I was getting great groups with the old arrows but I cant get new ones to fly straight. The arrows seem to be leaning left at impact and very erractic. Any suggestions or fixes? Thanks

You should have stayed with the XX75's.

Why would you make this change with the rut upon us? Good last minute luck.

I ran out of arrows. I loved the xx75s but need more.

The 2312 is a little weaker shaft, so that might be the root of the problem. You don't say how long of any arrow you are running, but one solution might be to shoot a shorter arrow shaftin the 2312 - which will effectively stiffen it. I have a 29 3/8" draw length, but can easily shoot 27.5" shafts due to the arrow rest being positioned at the back of the sight window.

Agree with Roskoe on this one. He hit the mark.

Thanks guys. In the past few hours I went back to my original setup for the 2315s and they are flying great. I think the 2312s are too weak. You guys are right. I am pissed that the jerk at the shop would even sell them to me. I bought a new bow and the arrows together. Went with the new octane hostage rest. Hated it...went back to the biscuit. Some people.

BTW, I have a 30.5" draw with 29.5" arrows. Looks like I could shave an inch maybe off the 2312s. Think that is enough to stiffen properly? Thanks

Take these bow shop guys with a grain of salt. Until you talk to them for a while and figure out how knowledgable they are, just in one ear and out the other. All of the bow guys I have met so far have been yayhoots. Their are guys out there who know their stuff, but be leary, their are alot of morons too.

I'm thinking if you could cut them back to 28", it would be enough. Another option would be to go to a lighter tip - like a 75 grain.

2312's are too weak, and you'll def need to shorten them up a good bit to make em work right. Stick with the 2315's....and xx78's are the shaft to get next time you get some. I can't believe he sold you those...you'd probably even be ok with 2216's, they will shoot good out of most bows in that range. The other bad thing about the ultralight shafts...they toast super easy. Good luck.
