Glad that this all worked out for you.
Sub half moa average is awesome for an out of the box rifle, and with factory ammunition.
I have a feeling that if you start reloading and find something your rifle likes even better those .161 groups will become much more common. I would expect single hole groups out of it with the right hand load. You already know it shoots the v-max well. If you consider reloading, consider trying a heavier v-max. Hornady makes a 40 grain with a higher BC than than the 32 grain. I would expect it to be less pushed around by the wind.
