Kind of surprised Remington Core Lokt are no in JBM's database.
According to Remington, their 7mm-08 140 CoreLokt has a BC of .390 and a muzzle velocity of 2860 fps, assuming you are not using the managed recoil stuff.
Punch those numbers in the JBM program I linked above, and make sure you put in an accurate sight height. For what you are trying to do, it is really important.
Set the table Range Increment to 20, and play with the zero range until the 60 yard figure is +1.5"
That should get you in the ball park, but you should reality check at longer range when you get the chance.
OK, I got bored and ran the numbers, using the 1.5" sight height, that is actually a really good hunting zero. The zero is around 230 yards, and the bullet is never more than 2.7" above line of sight out to that range, and drops to just under 6" low at 300 yards.
Now, you sights are probably not 1.5", so measure them, put in the altitude and temp of where you will be hunting, and run them yourself.
Again, once you have the results, you really should do a sanity check in the real world, to see how the prediction from the program matches reality. Some times it is spot on, sometimes.....not so much.
