Having seen the size of #7.5 shot I cant imagine that the #9 would do much good past about 10 yards or so.
I will stick to my trusty Beeman and my old Crosmann 766 for tree rat and gutter eagle control:-)
I have gotten tree rats at about 100’ with the Beeman and .22HP pellets

Beemans are excellent
I use it for varmint control at home. Too many houses around for pellets in most cases. I originally got it to get rid of grackles, which it did just fine.
