Thsee days all the precision actions seem to perform on par for ultimate accuracy. Certainly there are actions available for specific disciplines, however in general, I would say availability and features are the deciding factors. Stats are also a good indicator but the information can be misleading.
I don't think there is one action in the USA we can't bring in. If you find one you like and would like assitance, let us know. We have a few actions on route already...
