Almost perfect morning, wind was right, moon was full, ground was frosted. He came out from behind us and skirted my buddy for almost 60 yards without giving a shot. Finally came down the ridge line but turned towards the draw and watched him start walking away. Lost sight, then a minute later he apprehend much farther heading the opposite ridge. Took the last chance I had to shoot before he was gone; 130 yards Q/A and stoned him with the .450. 30 yards of solid blood and lung and there he was!
