I have a CVA Wolf that I got last year that shoots 1 inch groups at 100 yds. with Hornady 45 cal. 250 gr. SST sabots in front of 100 grains of Pyrodex. I tried 150 grains, but it would not group worth a dime. Plus, it was quite punishing on the shoulder. In hindsight, I am glad the 100 gr. loads group better than the 150's due to the recoil. I took a doe with it last year at 95 yards.
