You need a copy of EXBAL to use... It is a proven and trusted program with a great bullet bc index and factory load index.

I have shot this in out to 1150 yards at rocks and steel. Kills on antelope and deer at 732 yards and 840 yards.

not knocking you, just stating my data.

Start at equal muzzle energy

If you start the 140 accubond at equal muzzle energy as the Berger 168 VLD, then the Berger has less wind drift and more energy past 600 yds. Maybe for some reason you cann't get the Berger up to the same muzzle energy. For instance the magazine is too short so the bullet is too far back in the case. But my calculator says the Berger adds 100 yds to range for equal wind drift and 200 yds for equal retained energy at the 800-1000 yd mark.

I'm hoping to get the 168 to shoot in my 10 twist 7-08 AI. But haven't tried it yet.

Begers

The reason I switched was the wind drift period. I am dialing for everything and for vertical but wind bits in the butt. If you have to guess your wind drift the bergers give you a larger margin of error.

I switched after shooting Rock chucks in the wind. I was missing left then right all day tell i switched to the bergers. Sure it drifted, but I stopped missing by two inches.

Sorry for off topic.

I had a long throated 7rm with the begers seated to the neck junction.

Sendero Man what muzzle velocities are you plugging in for the 140's and the 168's? You should be able to run the 140's as least 200 fps faster than 168's. All the numbers I've run show the 140's to be flatter than the 168's out to 600 yards with the 168's having a slight edge in wind drift. After 600 is when the 168's start kick butt in drop and wind drift.

3200 for 140
3040 for 168

I agree .... go look at my data in the post below my target.... Out past 450-500 the VLD starts shining over the 140

I wasn't knocking you either, just stating the data I found. I believe field tested is WAY better then online calculators. I have both to try out in my 7mm Rem Mag so when I get them all dialed in I'll have some tested loads to post.
