I read it on the Internet! lol From reading stuff through the years I suppose. I know I would use whatever is in my hands but was curious on the 300WM. I like Woodleighs, but have only worked up a load for a 24" 30-06 and the 240RN that went 2400fps. I sold the rifle before I got to shoot a big hog with it. I also shot a lot of Nosler 200PTs and Sierra 200SBT in the 30-06. Killed a 300# hog with the Partition. Perfection. I figure in the 300WM, a similar bullet would work swell. I've shot a lot of big Plains game with the 300WM and the older Barnes 180xbt. Never recovered a bullet either. (Kudu, Blue Wildebeast, zebra all elk size), Red hartebeest (caribou size), Blesbuck (mule deer size) Impala and Springbuck ( Southern whitetail sized) and the big Namibian Gemsbuck (spike elk size) We used other calibers but the 300WM/180xbt was used a lot. For us, it was a great all around caliber. I figured many folks shoot those big bears with them?
