Basically what you need for a B&C or P&Y score is the following for your deer.
Inside Spread(widest point)
Main Beam x 2 (measure from the pedicle to the tip on the outside of the beam)
3 tine measurements per side seeing it is a 4x4
G1 (brow tine)
G2
G3
4 circumfrences per beam ( H1, H2, H3 & H4 on theRt and Lt)
Then total it up for your gross score. Deductions for differences between each measurement taken (except the spread) make up your net score.
Good Luck
