.300 Whisper - What do you use it for?

[mllm]

I talked with JD via email today. He confirmed corbon is currently not producing the 300 whisper. As stated previously, I don't trust the local guy to reload. I would like to have a hunting round for the AR as the 223 is really small. Although I have 100 rounds of the 223- ss109's, and they are the nato light armor piercing rounds, (so I have been told) I am not confident of it's clean, 1 shot kill on a decent sized deer or hog.
I guess my question at this point is, what are my true options on purchasing 300 whisper rounds somewhere. Other question would be, if not the 300 whisper, is their a whisper round (differant caliber) that is produced and readily available for those who do not load themselves.
Thanks for the link on the 300 options.
