Size of bullet for size of game
I was watching a video clip on the BOTW site. The guy took a 925 yard shot and harvested a nice bull elk. He was shooting a 6.5 284, with a 140gr Berger bullet. That bull didn't go far, maybe 30 feet or so before he piled up.
So, what I'm wondering is, that being the case, would I be safe to assume that I could use a 168 gr bullet in my .300 WSM and take game up-to the size of a Moose? Granted, that is assuming competent shooting and all that, proper placement, load works well in this rifle etc...
Also, for the smaller critters, what load would you recommend? Like fox, coyote, wolf size. I'm not noticing too many lower weight bullets for the .300 WSM, so I'm guessing that would mean I'd have to look harder or load my own. Or do I just stick with one (the 168gr Bergers) assuming they shoot good in my rife, that is, and use those for everything?
