You could try getting a tap and running in them.

I have had no problems with my Axis at all in fact I cut my second dozen and made them up a couple of weeks ago.

Have 11 with field points and 12 with broad heads and they all group together.

Mine are cut to 27 1/2" so I had room to play with when cutting them so I took 2" off the nock end and then cut to lenght so I am using the straightest part of the arrow.

All the arrows spin true with broad heads even the first lot that have been shot a lot.
