Gotta agree with math man. I have shot the 180 in a 300 win mag since 1980. I run these at 3025 FPS. I have shot deer from 25 to about 500 yards. The only bullet ever recovered was in the second deer it killed that was behind the first deer. The bullet was picture perfect mushroom. This is problem only 30 to 50 deer but is a pretty good sample for me. Ed k
