458 Socom should be in on that list. Great round and you can now hunt with an AR platform.
My boss has an AR in .50 Beowulf waiting for next year.
.50 Beowulf for deer hunting! LOL, from what I understand about the round that was designed to punch through and engine block, you should be able to shoot the deer in the front and have the round exit the back of the deer. Here is a quote from an ad for a .50 Beowulf:
"you heard right with the 380 grain solid brass Thor hammer round available from Satern machine you can do anything from knock a diesel engine out of a truck, put in a new door, split wood, even skin, field dress and mount a deer head on your wall all with just one easy trigger pull! "
Actually, the .50 Beowulf is, roughly, ballistically equivalent to .45-70.
