The imaginative process may help. Any fanciful or romantic notions you may harbor about these guns?
I dreamed that I got an interorbital shot on an up close mountain lion, a big-un. Hit him dead square between the eyes with a Navy (that’s a .36 for those who resist the notion). The skull slopes in that area, as is known. In this dream I was using my standard .380 and 24 graines and the ball bounced, … bounced! …, he kept a’comin and then I woke up. No wonder I carry something in .44 when I’m out on a scout.
At 1000 ft/sec a .380 (84 gr) produces 186 ft/lbs of energy. That is not overly much but plenty for Tutt and many others. Just for comparison - a 141 gr .454 gets 313 ft/lbs at 1000. Big difference. Anyone have an actual thought on this?
