If I recall the taylor KO formula is the bullet wt. in grains times the velocity in fps times the caliber in decimal divided by 7000 for grains per lb. It been a long time since I have worked with this stuff so don't hold me to that. The info should be available on the webb someplace I once saw a chart on some site that had all the popular caliber combos listed. As they say though the memory is the first thing to go and I don't remember what is second.
