Lets see , you've got 5 arrows that are sort of close ,not close enough , but are very cosistant in that each particular arrow hits the same spot each time . Conclusion , junk arrows . Get some allunimun or acc arrows that are spined correctly and have enough fletch on them , ie 5 inches . Get a half dozen if you dont want a full dozen , and Ill bet your groups get closer together .

Ammo? When you are going to the pro shop? If they knew what they were doing, you wouldn't need any of this info. If they can't figure it out on their own then you need to go to a different pro shop!

That is why it is called a PRO shop!

RE: What do you think is wrong here?
 

I've got some good news. I dug in and did a few more hours of shooting. I find this "broadhead battle" very tedious. Anyhow, I had a dozen arrows built for me back in May, and then bought 6 of the B-52 heads. I had the bowshop tune the broadheads onto 6 arrows that gave me the narrowest range of weights, all within a grain. Anyhow, in desperation I pulled out the other six arrows and started switching broadheads around. In the end, I got the two worst fliers of the original six matched up with arrows that flew well. I now have four arrows that fly to a "median group" under an inch, with the fifth and sixth arrows each grouping within 1 1/2" of the center. I wore out my block target; after about 200 hits it's starting to let arrows all the way through. I've got the second biggest model.

Ijimmy, I wonder what kind of carbon arrows you'd recommend. Mine are ICS Bemans.

Interestingly, Bow and Arrow mag came out with an article on arrow spine tolerance in their latest issue. I just bought it and read it about 4 times. While they show pictures of the ICS Beman arrow in the article, when they get to their fancy test, they don't include that arrow. Anyhow, the article says that spine consistency is the most important component to arrow accuracy, and that many/most carbon shafts aren't up to standard.

I'm very open to trying a different shaft NEXT year. I don't think I'd do well with aluminum, just because mentally, well I'll just say it, I'm kind of a spazz where archery is concerned. (I'll never admit to saying this if anyone ever throws it back in my face on another post!) I think the possibility that a shaft could get bent would absolutely make a nervous wreck of me. Every time I shot a bad arrow, I'd be convinced it was bent, then the target tension would kick in, and pretty soon I'd be convinced the whole stinking lot was bent. Then I'd toss my bow AND my nine-iron in the nearest body of water! Actually, I don't own a nine-iron, but you get the point.

Check out my tuning section on my website. It should offer some help as to what may be the problem
