Went to sight in my 20 guage USH yesterday.2x7 Leupold .Was shooting lightfields & hornady.SST first 3 shots with the lightfields were a 10 inch group at 50 yds. Im thinking not so good. Tried the Hornadys about the same. Group shifted a little left a little low. Im thinking time to go get some other brands. also The lightfields wouldnt eject. 3 more shots with each brand 8 inch group. Long story short. It took 20 rounds to tighten up into respectible group. 1 1/2 group with the hornadys & 2 inch group with lightfields.. Guns brand new. Im hunting with it on the 15th. gonna go with the Hornadys.
