I'm wondering what kind of bullets and loads to use to make my 300 Ultra Mag suitable for different game, from Whitetail to Grizzley. Yes, I know people will call me crazy, but it's what I have and dog gonnet I like it. I was thinking of loading down for whitetail, but heard that may negatively affect accuracy. I was also wondering if it was better to use heavier or lighter bullets on something as small as whitetail, as a heavier bullet would be slower and less explosive, but a lighter bullet would be less dense and have a lower momentum. Or perhaps I could use less explosive bullets, such as FMJ? I was a little worried when a friend told of a deer flipping over when hit by a 300 Win Mag. I've seen loads from 110gr to 250gr for RUM. Recoil isn't an issue.
