Thats not the actual formula, I was just showing the three ingredients, probably shouldn't have included the "x". The actual formula always favors the bigger diameter and heavier bullet, so the exact opposite to what you said. Hence why it also favors bigger guns. Its the formula that BASA use. I can find out what the actual formula is. Our Dangerous Game shoot is Group one minimum, so 0.330" and 225 grain.
