deer dude, seems u r mis informed, when i am shootin over 600 yrds it is imperitive that the shot be placed, and deer sir, a 30-06 at 600, well there is a contest, they call it the rainbow contest because of how high they are "lobbin" a 30-06 and its trajectary is that of a rainbow, which is in fact not horse shoe shaped, but if looked at from space is a complete circle, but everyone see's em as a horseshoeshape, and is why ya cant find the end of a rainbow...good luk on ur research.
WTH are you talking about here? I think you were half baked when you wrote this.
Fact... past 300 yards +or- you are "lobbin" the bullet in no matter what cartridge you are shooting. There are a few exceptions but the vast majority of cartridges will need compensation past 300 yards.
