I shoot the 175 gr duplex exclusively in my encore. Cecil gave me 3 to try at the range and I was hooked! The first doe was shot at 50 yds, she went 25 feet. massive damage, blood loss. I use them in our ranges muzzleloader shoots, and I can keep 3 rds almost touching on most days at 100 yds. They don't work for everyone, but they do for me!!
