Sierra's 3 BC's

After several hundred trial and error loads I found one that realy shoots nice in my gun, but I dont know which of Sierra's BC's to use.

300 WSM
155g SMK
3158 fps

Tactical shooting starting at 800yd's and moving in until 50yd's is reached.

My ballistical software only takes one.

    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.

    I am using Shoot! V3.2. Near as i can tell it uses G1 BC and has been right on the money for all the shooting I have done previosly.

    I also use the 5.11 tactical watch with Hourus Vision Software in the field as primary doping instument and a data card secondaraly.

    I would suggest using JBM and for whatever bullet you are using pick the "Litz" option from drop down box as that uses a G7 BC that Bryan came up with.
