i would take it toarchery shop or club..
you would be surprised after a few people look at it,they might just catch what is wrong...
our indoor archery has lots of people and niceplace to shoot...

if that does not work, i would send it to horton too look at...

i also saw this once reloading a 300 sav model 99..
we did everything to try to get bullets to come from left to center..

i found out it was a bent sizing die rod inside which was canting the bullet just a hair...

have someone stand behind you while you shoot, have them look at way arrow comes off the bow ..
you may see your problem right there..
if arrow comes out nice and straight,i would say its scope or mounts.....
