Hey Dumbschit...
I've been shooting seriously for about 35 years..
I outgrew depending on 25 yards zeros for shooting at anything PAST 25 yards about 34.5 years ago..
YOU should try growing up and learning a bit yourself, rather than relying on the regurgitated horsechit you Google up and foist on folks here..
You are a total joke..
