.50 Beo, .458 SOCOM, .450 Bushmaster...
Keep in mind these are all "short range" cartridges.
There's only so much you can get out of the AR-15 platform.
If you want to push big bullets fast, you need case capacity, period.
Then you're into the AR-10 platform...or even an M1A...
Why are you set on a semi?
Sounds to me that your needs, and budget, would be better suited to a bolt action.
