Multiple shafts grouping together?

[JMSmithy]

Is this possible??

I'm shooting a 56" Black Widow PCHX in Birdseye Maple (I own a sugarbush  ) 55#@27". It's most happy braced at 8 7/8-9". Shooting arrows 29.5".

Here's the issue, I'm shooting Beman MFX 400, Easton Axis Traditional 400 AND ABS GrizStik Alaskan tapered shafts and they all seem to be impacting the same, assuming I do my part that is with a smooth consistent back tension release. ...

Is this possible I know I'm doing it but ...

Thoughts comments are appreciated

All look good....of course my shooting could be better but all seem consistent.
