They shot pretty good from my ultra varmint 223 as well with h322 anywhere from 22-24.5 grains, but I didnt find them to be explosive, infact I had some quite a few ricocet, performance on groundhogs was bad as well, single hole in, single exit hole out, about like a soft point, but i may have gotten a bad box or somthing, i read alot of reviews and everybody seemed to have good results exept me.
