Well I guess I'll play devil's advocate
If you're looking at a max range of 400-500 yds, you aren't going to need a uber BC VLD... not necessary; especially with the stated velocity of 3700fps! I will tell you, I would keep 500yds as an absolute max due to the poor BC & the effects wind will have when that velocity starts to fall off.
The 100TTSX @ 3700fps will level any deer on the face of the earth in the 400yd area. Bang,
------------------------ > dead deer.
The 100grainer will have less drop to the 4-500 area, & (without running the numbers myself) the TOF should = equal or better the wind drift of the heavier bullets.
Angus was spot on about using your power ring (assuming SFP) to run you 3-9 as a "poor man's Horus". It will be time consuming, but will work just fine.
If you intend to hunt gamer bigger than the largest deer, I would step up bullet weight, if you don't, load the 100's & never look back.
