Will be picking up a HW30s in .177 soon for some short distance pesting. Looking at doing a Vortek kit on it to bump the power a little bit. But, also saw mention of a o-ring tune done by Ed Canoles where guys were gettting in the mid 600's w/ 8+ grain pellets.
Can anybody shed some light on their experience? Thanks!
