[QUOTE="Darryl Cassel, post: 1323, member: 34"] [b]Re: This & That....A Layman\'s Long Range Rifle?[/b] Hello Tom I have to agree that the velocity is not at 3300 FPS and that explanes the amount of drop. Please refigure your 1 1/2" high at 100 yards statement. I think that's off quite a bit if I read that correctly. If the 180 Gr bullet (Gameking for instance) with a BC of .545 was 1 1/2" high at 100 yards and at 7000 feet elevation was shot at 3300 FPS you will be dead on target at 275 Yards, NOT 500 yards. Without making any other scope settings, At 300 yards you will be -1.22" low, at 400 yards you will be -8.83" low, at 500 yards you will be -21.17" low, at 600 yards you will be -38.74" low. Check your ballistics program. I just ran three seperate programs. This is with no other changes other then being 1 1/2" high at 100 yards to start with. Wouldn't want a newbie to read that his rifle will shoot that flat at 500 yards with only being 1 1/2" high at 100 yards. That's simply not factual or ballisticly possible with that bullet and even that speed. I too have been LR and ultra LR hunting for many years, especially in your fine State. I'm not sure of how many MOA is on the original posters scope verticle reticle, top and bottom spacing. I click to all yardages and don't trust a rangefinder scope because of the distance we shoot. If the above ballstics are close to what he shot, this could explane why he was low, but not 60" low. About 38.74" would have been closer to the fact of what it should have been.
