I have a Wolf also and I really like it, only had it about a year. I'm going to be useing it for both the regular gun and the ML seasons this year. I'll be shooting either 100gr American Pioneer or T777 pushing 300gr Barnes expander MZ. I don't have much info on shot groups but I've been hitting small pop bottles at 50yds and right now thats good enogh for me as most of my shots will be that or less.
Good luck with the Wolf, let us know how it works for ya
