Till then Brian Litz G7s are probably the best option and then testing testing testing. Knowing what the number is helps if you plan on tweaking it a little.

Shooting to 500m and tweaking the BC to better fit your results may put you out, further out. Maybe not much, but maybe enough. It's ok as long as you know your tweaking your BC to suit your chosen range, and the atmospheric conditions you worked it out in.

I shoot with a droll little chap that likes to point out little things make little differences at range, and mostly little differences can be ignored. But, lots of little differences stacked together equals a big difference.

It is surprising how much the BC changes as the projectile slows down.

The big 375 projectiles are usually pretty good right out to 2000-2200 yards then it all turns to poos & you need to add more & more, 6moa from memory at 2500 yards, that is quite a bit nearly 4metres, at this stage I only have G1 BCs for them.

I guess the small ones do the same thing if you can be bothered shooting them far enough & can see the strike.

I have better results with Shawn Cs stepped G1 BC over Bryan Ls G7, with the 300 Bergers, there is very little in it until you way out there.
