I'm starting to do some patterning now, with loads I can find. problem is, I can't find many if any suitable shells around here. I've read most of the thread about patterning, wasn't sure what my bore diameter was, thanks. I still may borrow my buddies choke to try, my main concern is safety dropping to that tight of a choke. I got some dead coyote loads on the way to try, then after that I'm gonna try whatever I can find through these two chokes. then maybe try some other chokes. I kinda wondered if I may be chasing something impossible, I did read on that thread that 5 pellets at that distance is pretty good. I didn't want to drop too much money on this gun, when my bike sells I'll be getting a new autoloader, may be doing this all again. I still want a good backup though. thanks grizzly, I'll have to check him out.
