Hillbill, I use JBM calculations for my drop charts and have found them to be pretty accurate. I have found that with my weapon though, I add .1 Mil to whatever JBM states. It was a 20.1" drop or 1.6 Mils. The wind was coming from directly behind my and straight to the coyote so I did not have to worry much about wind drift.
glanceblamm, the land owner is putting me onto two other farmers' land to take care help with their G-Hog probs.
