I have the USHD in 20 ga. Shot my first deer with a shotgun this year. The doe was at about 30 yards which obviously wasn't a tough shot. I was using the SST's, but eventually found inconsistant groups from the SST's. Every bunch shot different no matter if they were out of the same lot. I guess every gun shoots different. I would love to find a round that shoots as consistant as the Remingtoncoppersolids out of mine at 100 yards, but the consistancy can't be beat. Again, all guns are different. The Lightfields also shot well, but dropped quick at 100.
