I just ran these on a ballistic calculator

Range - yds 0 50 100 150 200 250 300
Velocity - ft./sec. 1500 1274 1109 1002 928 869 820
Energy - ft.-lbs. 1998 1440 1093 892 765 671 596
Path - in. -1.5 1.9 -0.0 -9.0 -26.6 -54.3 -93.5
Drift - in. 0.0 0.7 2.9 6.4 11.0 16.4 22.8
Time of flight -sec. 0.0 0.1 0.2 0.4 0.5 0.7 0.9

I gave the slug a weight of 400gr, diameter of .62 and a bc of .12 which should be in the neighborhood.
The drift is with a 10mph wind and a 100yd zero

Sorry but I couldn't get the table to format.
