Am I right or wrong? Any suggestions? Also the rifle is a Remington 710 so I was a little iffy about putting a 200-220 grain round in?
First, each weapon is an inanity unto it's own and will react differently with different components.
This is generalities only, no set laws.
Heavy bullets will hold energies/velocities better.
Heavy bullets are harder to get going, normally slower out of the gate.
Lighter bullets start off faster/easier.
Lighter bullets drop velocity/energy faster.
Boat tailed bullets have better ballistics coefficient.
Better ballistic coefficient bullets hold velocities better.
Greater velocities, the flatter the trajectory.
An item (bullet) dropped from your hand will hit the ground at the same time as one fired from your weapon (from the same height, over flat ground).
Everything in loading is a compromise.
More pointed data.
Boat tail bullets don't add much at ranges less than (insert range - 200 yards or 300 or what ever the prevailing view of the person picking the range).
The general consensus (less people will disagree but many will) is bullet weights of 165 to 180 grains are better for longer shots at 30.06 velocities. 150 grain bullets and less don't carry as well and 220s just don't have the velocities.
Now, 800 yards is a long way. To shoot longer ranges, you must learn your rifle very well, practice a lot and have very, very consistent ammunition. I'm not going to say that commercial stuff won't do the job, but that quality of stuff is going to run a pretty penny. Load you own, to get the quality you will need to do any good, constantly, at 500 to 800 yards, without breaking the bank. Start loading with cheaper bullets that are close to the same weight of what you will want to do your long shots. When you get your 100 yard grouping down, then move to the better/more expensive bullets and start extending your range, little by little.
Hope this was of some help.
