[QUOTE="4mesh063, post: 17422, member: 941"] [B]Shooting a 35 degree angle at 600 yards is roughly a 540 yard shot using a cosine angle. The time of flight of the bullet will actually be longer than flat 540 yards shot. So would you trust a cosine indicator for a shot like this?? That's the real question?[/B] I guess I don't follow you on this one. If you range the target, the distance is the distance, regardless of the angle. Now, if you are ranging the first floor of a skyscraper from ground level and decide to shoot a pigeon at the 40th floor, now I see a change of range, but, If you have a Leica, you can range again to the bird and pow. You also mentioned above (I don't have it in front of me) but something about the additional drop. There is no additional drop. If you are refering to the shot on an incline, that path will allways be high, though you will be hard pressed to build a gun capable of showing the difference from shot to shot. For that data you would have to provide some ballistics. Cal/Weight/BC/that sort of thing. Now, unless I don't understand this cosine thing (I think I do) the 600 yd shot at 35 degrees relates to 491yards ground distance. I guess I have to do some reading on your gizmo you're talking about. It doesn't sound very fun to me. Shoot at stuff that doesn't run after the first round! Hehehe... [/QUOTE]
