Great buck and I've had similar success with the LRX's.
I've been hunting with the 127 LRX in my 6.5-284 since they came out. I've shot about 10 deer and numerous hogs with this bullet and they have all been DRT, high shoulder for deer and shoulder/head for hogs. Like you, most of my shots range from 100-300 yards here in the SE. I can't think of a better bullet for those ranges.
I also agree that at extended ranges (500 plus), I worry about having enough velocity to open them up, effectively. Therefore, I have a great load with the 140 VLD. The great thing is that the 127 LRX running at 3150 and the 140 VLD running at 2950 have almost the exact same POI at 100 yards. Dope out to 500 is so close I don't worry about the difference, and set up my turrets for long range with the VLD, should the opportunity arise.
127 LRX, 3150 fps, drop at 500 yards = 2.2 Mils
140 VLD, 2950 fps, drop at 500 yards = 2.3 Mils
(windage not withstanding)
The best of both worlds is nice and I've had success with both types of bullets. In the proper circumstances both types of bullets shine.
Bulletproof samples does this, you can get them from BrownellsThanks Broz, I will give the 180's a try. I remember seeing a company that would sell just a few bullets for testing, going to try and look them up. I'm working on the 190's and 210's in my 300WM based on the results you posted with the heavier bullets in that caliber.
