I ran across this locally and thought I'd give it a go in the 455...dime sized groups at 50 yds and 1" groups at 100! It's a little spendy to not say"super duper extra mega match" on the side of the box but its strong groundhog medicine inside 50 yds. and I think I just might like it for tree rats in the fall. Anyone else playing with this stuff and what kind of results are you getting?
