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

Lower draw wieght or lower tip weight, your arrows are too weak now.

Take them back to the guy at the shop and tell him he's FULL of it??? I gave up on aluminums a LONG time ago, because I could NEVER get them restraightened after a bad shot or two, so I've been on the Carbon Bandwagon since the "beginning of time" or so it seems, circa 1996 or so. Not sure what your DL is, but for your set-up, you need a 400-ish spine, which is gonna be a 2117, 2216, 2315, 2314 are all decent, that 2312 is a more along a the .425-ish spine range, which as gonna fly erratic.

I agree, those are way underspined, especially for broadheads and too soft for hunting anyway. That guy just sold you what he had instead of telling you to go elsewhere and get what you NEED.

Yeah, I agree with what everyone else has already said about your current shafts.I would get someCarbons, perhapsGoldtips or Carbon Express. Personally, I love the CE's, they're one heck of a shaft, but I know a lot people who swear by the Goldtips.

XX78's are a great arrow if they're spined right for your bow, which those weren't. If you get them in the 2315's or 2512's you'd be set but going from a 2315 to a 2312 isn't even close to "similar". You need to re-evaluate your relationship with that shop.

No doubt. you should be mad over this. Thats a difference in spine going from .340 to .420".

Another agreement 2312's are a limp noodle compared to 2315's , I shot aluminum for years , never did like the thin walled shafts , they bend just looking at um
