Tim,
I am so glad to hear you say that. You're a man after my own heart. Unlike you there are many self professed gun experts out there who deride the AR platform as a viable hunting wepon. To me a gun is a gun is a gun. What it looks like is immaterial. I think Martini Henry rifles are great looking, I lust for an FN FAL, I think Walker Colt's are gorgeous and I think the AR platform is a very ergonomic and versatile platform.
Talking about the .458 SOCOM in particular, it is designed to provide a lot of stopping power at close range. As can be seen from the video, even sand filled concrete blocks are not an obstacle for long. From a military standpoint, since many of the loads available are subsonic, use of a suppressor becomes easy. The advantage of the caliber is that it can use the large number of 45-70 Govt bullets available on the market.
Hunting and other bullets upto 500 grains are available from SBR in expanding and solid versions. A 500 or 600 grain bullet travelling at 1000 ft/sec put out a lot of wallop. Keep in mind that this is a short range gun (150 yds or so). The looping trajectory of the heavy subsonic bullet would require a great deal of holdover after that. The AR platform is not real heavy.
This particular example made by Rock River Arms is 7.6 lbs sans scope and mounts. The buffer spring does help in spreading out the recoil over a period of time, making it feel less sharp than it is. I believe this particular gun came with three different springs.
I don't know about cast bullets. You have a point that lead shavings might affect the gas system. I seems that all the bullets offered by SBR are jacketed. i wonder if just plating or copper washing the lead bullets would remedy the problem. That would be a lot cheaper than purchasing jacketed bullets.

Rup,
You can see more info about this particular firearm above.
The beauty of the AR platform is it modularity. As you can see from the video when the soldier brings the .458 SOCOM upper out of his backpack and puts it on his lower assembly, it's a quick switch between calibers.
You buy the Lower Receiver (this is the serial numbered part of the gun). Then you pick out the furniture, the barreled Upper Receiver in the caliber of your choice, and the sights. Switch magazines and you're ready to go.
This is the Lower Receiver:
Buttstocks are available in a number of styles:
Add your "upper" in whatever caliber, barrel length, etc.
pick your iron sights, scope mounts, etc.:
You can build and customize your rifle as there are literally thousands of accessories and parts available from different manufacturers. Switching "uppers" takes seconds. You can have one lower receiver and uppers in many different calibers (from .22 LR and up) if you so desire. Aftermarket trigger assemblies, handguards, picatinny rails, you name it, are available.
