Here's my setup:

62" Pronghorn L/B 58@28, Right hand
Draw length 28 1/2 inches
FF string
Brace height 7 1/2 inches
Nock height 1/2 inch
AD Hammerhead arrows, full length
Standard insert
150 gr points

Also have some AD Traditionals, full length with the 100 gr. brass inserts.

Here's the issue, the shafts are hitting the beveled edge of the riser about 4" in front of the wrap.  I raised the nock height to over an inch and flight has improved but arrows are still hitting the riser, this is happening with both the HH's and the Trads.  Adding point weight has also helped, but I don't want to hang 350 grains on the end of the arrows for this bow.  The point of buying the AD's, which are tapered, was that they are supposed to shoot with a wider range of point weights and fewer tuning issues.  

Do I need to go back to square one and try a different arrow?  Or, can I get these arrows to tune?  Thanks for your advice!

Chris,
I own two pronghorn similiar to yours and haven't had too many issues tuning them.  However, I shoot Axis 400, 100 grain insert, and 150 BH.  My brace height on both bows is right around 7 inches.  My red elm bow I could not get an arrow to fly true to save my life.  i kept cranking the brace height up but it never cleared up.  I then started cranking it down and everything straighted up.  I know a few guys that shoot their pronghorns around 7inches but I also know a few, mainly shooting woodies, that like theirs around 8 - 81/2.  If you know anyone with different arrows give them a try, but like me maybe enough tinkering will straighten everything out.

good luck and enjoy the pronghorn.

Chris, I just picked up my first Pronghorn. Its 62" 54#@28". I draw 27 1/2".  I'm shooting Trad Only 400's out of it cut 28" with 260grains upfront and they fly great. 3Rivers is the only place that sells them but they fly great out of all my bows from 52# to 57#. Hope this helps. Fred

take the time do it right from the start good luck

Thanks for the info guys.  I'll keep playing with what I've got and hope it works out, otherwise some new arrows may be in my future!

another thing to consider is maby its something you r doing possibly torquing the bowcould do this as well.

Chris,
My recommendation would be to try a lower brace height.  On my Pronghorns (3-pc.), I shoot a brace of 6 3/4".  Herb Meland suggests 6 3/4" to 7".  Hope things work out for you.  The Pronghorns are a great shooting bow!

my 1pc pronghorn 57@28 60" is shooting well with 6 7/8 brace height 1/2" nock. i shoot 30 1/2 gold tips 5575 100gr inserts and 125 points. also have an sbd bowstring.

I have a 1 piece pronghorn that groups great with Easton Game Getter 500s and 150 up front. its 61# with 6-7/8" Brace height.

A quick update.  I lowered the BH to 6 15/16, arrows are shooting better and the bow is quieter.  Played with the nock height and it is still almost an inch, 7/8 I believe.  The arrows still kick to the left, though they don't contact the riser nearly as bad as before.  So, I'm thinking I need to work on my release and fiddle with the setup some more.  Just to make things worse, my left elbow is acting up and is making it hard to shoot.  Thanks again for the replies and advice!

ice the arm and see me i a few days id sugest working on you form and there are plenty of threads in that subject .

My nock point is about 5/8 - 3/4 and that works great for me.  Another thing I did is open up my nocks a little bit.  The nocks on my axis shafts were a little too tight so once I relieved some of that pressure off the string my arrows flew even better.  Like mentioned before some form, torque, or release might also play a role.  good luck and enjoy the pronghorn.
