Just for fun I decided to try some reduced loads in my TC 50 flinter. 40 grains is a tack driver at 20 yards out of the GM barrel. I thought I would see if that load would kill a lawn mower. Shot an old junk MTD rider through the hood with it. Went through the hood, both sides of the air cleaner, and knocked a hole in the cylinder. That is way more damage than I was expecting with such a light load, but it sure was fun.
