I have an Horton Explorer HD 150 with the Horton 3red dot scope.The first time i shot it, it was shooting great.But today and yesterday it was shooting very bad.I completly missed the target 2 times at 20 yds and missed at 30 yards.I had it zeroed dead on at 20 yds then i back off to 30 and completly miss the target.I had a good rest so i know it wasn't me.Anybody else have any experience with these scopes?What scope would you reccomend me getting?Do you think that the scope is causing the inconsistancy?
