Re: What it takes to get to 800 yards
Some of the long timers may chime in on this one but I will tell you how I figure it out.
This seems to be a question that is highly depended on bullet. A good high BC bullet will carry it's energy out further than one with a lower BC, generally speaking. This is why certain bullets become more popular for long rangers but it may not be a bullet that a convential range hunter would use.
So what I do is find a good ballistics calculator like the G7 Ballistics Calculator located in the brown toolbar up above and start plugging in numbers. Find a good bullet that you may want to use, do some googling and see what guys are getting for real world velocities from a gun like you own, and see what you come up with. I say a gun like your because one guy might get 3000fps with a custom gun with 30" barrel and so on, and I might just have a standard factory 24" type situation. Then you will have a better idea of what your numbers will be.
As far as energy stuff, that is contrary to interpretation and bullet type. The very broad general concencus I have read is 1500 for elk, 1000 for deer, but everybody, including myself will have a different opinion one way or another about this.
I can't recommend a good 180gr bullet for a 30 cal for you because I don't own one and I don't want to mislead you. Most guys shooting a 300 win mag right now are shooting that 200-215gr bullet for higher BC and less wind drift, but I don't know if the 30-06 would drive that big of a bullet with enough speed to make it beneficial.
