Re: Sierra's 3 BC's
Since you are shooting at a high velocity use the highest bc. This will give you a good approximation of performance and get you on paper.
Next, get out and shoot the load and get your actual drops. Now you can tweak the bc to correspond with your real life performance.
I use a ballistics software than actually uses all 3 bc's.
