LOL!
Yes I have...this project has been about 4 years in the making.
A friend of mine e-mailed me feistyrooster's .300 FireBall page one day and I sorta got hooked.

Don't get me wrong I love my ARs in 5.56, but deep down inside I will always be a .30 cal kinda guy. I was raised on .30 caliber firearms and fondly remember taking my first deer with my father's old Winchester 94 in .30-30 as well as hunting for Louisiana wild pigs with his Remington Woodsmaster in .30-'06.
This was the perfect set up for me, a .30 cal AR with punch in supersonic (out here in NV I want to use it for coyotes), as well as heavy grain bullets for subsonic use. The fact that it just required me to re-barrel one of my ARs and I could use existing AR mags/accessories and I have plenty of .30 cal rifles that I am already loading for just made it that much more fun.
I did a ton of research and then went about gathering all the goodies I would need. In particular I was very fortunate to have acquired a 5 gallon bucket full of once-fired 5.56/.223 brass. I'm glad because I am a prolific reloader and did not want to dip into my 5.56 brass for this project.
Plus during that time I also started casting my own bullets...again I happened to have been fortunate enough to inherit almost 500lbs of wheelweights. I am really looking forward to shooting my own homemade projectiles through my own reloaded ammo.
This forum in particular has provided a wealth of information and there are some really knowledgeable people on here, I am grateful to all of the members here.
It's been a long road and I have had a great time doing the build on my AR and turning all of that 5.56 brass into .300 Whisper brass (2200 rounds!).
I am definitely looking forward to making all of that brass into ammo.
Within the next few weeks all of the research will be done and I plan on using the rifle for coyote shooting, hunting and an all-around fun gun. In the future, I'd really like to take deer and hog with the .300 Whisper
