My son has killed a huge-bodied bull, a brown bear, several caribou, black bears, a mountain goat, a Sitka blackmail, and maybe other stuff I forgot with a 25-06 and 80gr ttsx... seems that putting the bullet in the right spot allows it to work
Your son obviously doesn't know what he's doing.
And if anyone wants to read the OP, he wasn't asking opinions on the .308 as a moose cartridge. He was asking about bullets to use in the .308 for moose.
Why anyone would opine on its sufficiency is a mystery, he seems to be comfortable with it. So if we don't care what cartridges other people use, what's up with opinions on his chosen cartridge? He didn't ask that question.
