Both of my HW30s are as smooth as my Walther LGV .22 so imo don't need tunes out of the box. As far as galling my last one took about a tin of pellets to wear in. Are you going with the standard or deluxe ?
BillBack to your original question, I think if you took a poll, you would find fewer people found a tune necessary for their 30S than did for the 50S. That has been my experience personally and I own both. Just sayin.
