I was watching a show I can't rember if it was on youtube or tv, however a man was showing the effects of corolis on poi. He shot 5 shots at 1000yds directly west that grouped 8" low and 5 shots at 1000yds directly east that gropped 3" high. I have never figured in corolis as I shoot 500-700yds and felt at that distance it didn't make much diffrence however, I have found that at one place I shoot(where I sighted in my rifle that i'm nailing it at 500yds and another place my shots are low at same range. This gentelman also stated that rifles should be centered either north or south but to my mind if you do that arent you just trading elevation for windage. What are yals thoughts on coriolis and at what distance do you consider it? Brad

I watched the video and was scratching my head. The comment "you could have almost a full minute of correction at 1000 yards dependent on your zero" left me dumbfounded. What the heck kind of east/west zero are these guys suggesting????? A 1000 yard zero? The video does show a good prediction of hitting high or low due to extended range dependent on target direction.

It is easy enough to check the POI for your set up using a ballistic program like Shooter, and entering the latitude that you hunt and the azimuth for each; north, south, east, west. Hunting out to 1000 yards I personally don't bother with it. For longer range shooting out to 1500+, I do use it.
