Field points VS Broad head POI?

And if all else fails, spin test your arrows. You may have a situation where not every broadhead seats perfectly on your arrow, causing the bh to steer. This will generally cause bh's to group poorly in addition to not grouping with fp's. Get a G5 arrow squaring device to true up the end of the arrow. Cutting arrows perfectly perpendicular is hard to do even with a proper cutoff saw.

I tried to get my fp and bh to hit the same point of impact last year and it never happened. I moved the rest every which way and it didn't help. I bought different spine arrows, Differemt lengths, walk back tuned, French tuned, broadheads tuned nothing helped. I saw arrowsmiths post on bare shaft tunning last month, went out and bought a portable press and started tunning. In one afternoon I accomplished what I couldn't the entire year before. Thanks for posting up such great info arrowsmith.

Teach a man to fish (learning to tune your bow yourself) ....you can make your bow shoot well for yourself.
It makes you feel good to do it yourself and get results....don't it ?
Like I have said before.....the legendary Easton tuning guide that is flashed on every archery forum around when tuning is mentioned can frustrate the heck out of you. It only addresses a small portion of the tuning process.

And remember you can quickly Weaken spine with a 125 grain tip , and you can stiffen spine with 75 grain

definitely some great advice and some terrible advice on this thread.
First what your seeing is normal if you haven't taken to the time to tune the bow. where your broadheads are hitting will tell you whats wrong . . . could and probably is a spine issue. I'd say absolutely do a walk back test and absolutely move to broadhead tuning.
Last, MANY and I mean MANY times the answer to bad broadhead grouping is move to a mechanical it'll solve the group problem. yes it absolutely will at the cost of penetration. how many times you see a post on here by someone saying they can't stand mechanicals because they get poor penetration? A tuned bow will shoot a mechanical AND a fixed in an optimal way. . . . . you want penetration put all the power on an arrow that is flying straight. You rely too much on your vanes to correct the arrow flight and you are going to lose penetration with a mechanical. Easy to envision . . . . a head hitting straight with an arrow that is flying straight vs a head that is hitting just a bit off with the tail of the arrow off you can imagine that it won't work at its ideal.
torque and all of that is a factor, certainly should always work on your shooting form. But I'd bet with a field point you do a walk back and you'll find that your arrow is drifting one or another direction. Fix that then shoot broadheads and all you need to do is adjust the weight to figure out whats going on with your spine.
