[QUOTE="tysue, post: 123118, member: 6525"] I never fails to amaze me that folks will go buy a monster masher round, like the 338/378, then want to shoot groundhog bullets in it. I have talked to the bullet companies and all of them say anything less than the 250, except maybe the Barnes X or Nosler are made for deer, and then if shot from the standard 338 or 338/06. Speed them up and are even less reliable. Elmer Keith designed this cartridge and said to use NOTHING less than a 250 in it. The lighter bullet lose velocity fast (someone here just said that), and lose energy fast too. Speer told me that no knowledgable 338 shooter would shoot anything less than the 250s and the 300s better. I hate to say this, but think a lot of the lighter bullet choice has to do with the recoil going up. But using a light bullet, like the 200-210s in the 338, especially one like the 338/378 akin to shooting 125s in the 300WinMag. Okay if you're hunting ground hogs, but not Elk.
