[QUOTE="Greyfox, post: 893477, member: 10291"] For the two loads you are asking about using Berger VLD's at 5000 ft, 50F, at 1000 yards, 100 yards zero. Here is the comparison: 130 VLD at 3250 FPS. Drop 21.4 MOA, 10 mph wind 5.1MOA, 1730 FPS, 864 energy 140 VLD at 3080 FPS. Drop 22.9 MOA, 10 mph wind 5.3 MOA, 1731FPS, 932 energy They are pretty close with a slight advantage in energy going to the 140 and the 130's shooting flatter at the midranges. I like the 140's because my rifles give better grouping at long range but this may not be the case with all rifles. Between the two bullets I would go with the the best accuracy at long range. I do think the terminal performance on game with the VLD's is better with the 140's in that they seem to hold together better at the shorter distances at a more moderate velocity. At long range the higher sectional density gives good penetration while still expanding and doing a lot of internal damage. If elk at +500 yards was my quarry I would prefer the 140's for this reason. I have had outstanding performance on deer sized game from 50-1000 yards with the 140's running in the 3000FPS range out of my two 6.5x284's. [/QUOTE]
