I bought a couple hundred round to use for coyote at less than a hundred yards. They were accurate out of my old marlin. I filled milk jugs with water and fired from 25 yard. It went through the first three and settled in the forth. The recovered bullet expanded to about the size of a dime. Not a very scientific test, but has put down several coyote in the 30 - 40 lbs. range. I would but them again.
