Lol. Yea, they shoot the same bullets. I'm referring to the lenght of cartridge.
Also, the 7mm mag or STW is plenty of knockdown for an Elk. I would load a hot load of 150 gr swift scirocco in my 7mm saum @ 3100+fps and go get one. I dont like the added recoil of the 300 win mag or a 7mm stw. Recoil hurts accuracy and to someone who's a 1 time elk hunter, you need all the accuracy you can get on a long shot. I can't imagine how anyone would think a 7mm mag is insufficient for elk. 160 gr nosler accubonds would wrok better maybe. about 3000fps and a better ballistic coefficient than the 180 in 300 mag.
