Velocity, Energy, and trajectory are correct, the rest is relative guesswork. A lot of energy out to 550-yards with a Ballistic Tipped bullet.
The 280 Remington 140 BST Ballistic Silver Tip (Winchester Bullet) is pure Deer dynamite, --you got to love it!

The .280 Remington caliber with the above 140 grain BST bullet is an excellent deer cartridge!
With properly placed shots, this bullet and cartridge combination should anchor deer on the spot!

Rick Jamison writer for Petersen's Hunting Magazine, July 2002, p- 20, Guns & Loads Article Long Rangers,  - http://www.huntingmag.com  says in essence that for deer sized game you need a minimum of 1000 ft/lbs of energy and 2000 ft/sec velocity at the impact range for adequate bullet expansion. The bullet needs a sectional density between .215 to .265 and a high ballistic coefficient for long range shots.
This is a great Hunting Magazine, I used to subscribe through the local school magazine drives.

You can look at the various ballistic tables I have on the Net and determine the approximate outer range limit your cartridge and selected bullet will be capable of killing a deer with a well placed shot. If you can't put the bullet in the vital kill zone don't take the shot no matter how capable the cartridge you're using is at that range.

Running shots are a lot more dangerous, background must be clear! Pay attention to your skill level, don't take running shots if you're not confident you can make killing shots! Lead is in feet, use deer length leads at the longer ranges. Broadside 90 degree angle shots. Limit running shots to perfect conditions and 100-yards and under! Bucks will average six and a half feet in length, big does nearly 6 feet. The lead is figured from the chest, just behind the shoulders, subtract –2' feet from nose leads.
At 45 degree angles cut leads in half. This merely gives you the bullet flight time and lead at the above yardage's.
