I have a new SWAROVSKI 6-18X50 HABICHT TDS and was looking at the ballistic calculator for a 300 wsm. For each power it changes range in yards on the TDS drop. How can you keep up with this in the field.

Example 6 power

100 yard zero
Line 2 402 yards
line 3 661 yards
Line 4 574 yards
line 5 1008 yards

8 Power
100 yard zero
Line 2 344 yards
Line 3 561 yards
Line 4 722 yards
Line 5 869 yards

10 Power
100 yard zero
Line 2 305 yards
line 3 493 yards
Line 4 637 yards
Line 5 770 yards

12 Power
100 yard zero
Line 2 280 yards
Line 3 445 yards
Line 4 574 yards
Line 5 696 yards

14 Power
100 yard zero
Line 2 260 yards
Line 3 409 yards
Line 4 527 yards
Line 5 638 yards

16 Power
Line 2 245 yards
Line 3 380 yards
Line 4 488 yards
Line 5 592 yards

18 Power
100 yard zero
Line 2 232 yards
Line 3 356 yards
Line 4 457 yards
Line 5 553 yards

Most of hunting in GA and Ky ranges from 100 yards to 600, I printed data for each power. If you have any experience or knowledge with this scope , please help me determine the best way to use this in the field.

Thanks for your valuable time,
Donnie
