With a bit (a lot) of fiddling, I managed to replicate winchesterds ballistic info in hornady's software, giving me a fully stocked ballistics chart, out to farther than I care to think about. The only discrepancy is that i had to add 23 grains to the slugs weight to get the KE and Velocity to line up, and i had to tinker with the ballistics coefficient ( Since win. didnt give one). Hope it isn't TOO illegible. 
Ballistics Calculation
Input Variables Firearm type Rifle- Sight Height 1.5
Bullet Weight (grains) 450- Ballistic Coefficient 0.095
Muzzle Velocity (fps) 1400 -Temperature 60
Barometric Pressure (hg) 29.53 -Relative Humidity 78%
Zero Range (yards) 100 -Wind Speed (mph) 0
Ballistics Table in Yards- BRI Sabot Slug 450 gr., 0.095 B.C. www.hornady.com
Range (yards) Muzzle 50 100 200 300 400 500
Velocity (fps) 1400 1154 1007 845 734 644 565
Energy (ft.-lb.) 1958 1331 1013 714 539 414 319
Trajectory -1.5 2.5 0.0 -31.7 -109.6 -248.0 -464.4
Come Up in MOA -1.5 -4.8 0.0 15.1 34.9 59.2 88.7
