My son and I each took spring bears this year with my 300 WSM, mine was called in at 80 yards, his was taken at 125. Both were shot with a 190 VLD at .020 jump, over 68 grains of IMR-7828, WW cases and CCI250's. 2900fps. Both were dead in their tracks, and both tumbled to the bottom of the canyon lol. So far, no luck finding a fall bear, but we did call in a cougar on our last trip out. It didn't survive a head on collision with a 140 Accubond out of a 6.5x284. He has since bought a 300 WSM, so it'll be interesting to see how well my pet loads work in his rifle.
