For the AR-15: .30 Gibbs Short?

jkpq45 · September 24, 2013, 08:32 AM

Hi All,

I've got a crazy idea cookin', mostly from my surplus of .30-06 brass and my .30 Gibbs Reamer laying around.

If I cut a .30 Gibbs chamber to a brass depth of 1.750", is there any reason I couldn't:

1. Use either .30-06 brass or .308/7.62x51 brass as the parent?
2. Feed the cartridge from a standard AR-15 magazine?
3. Duplicate performance of .300 Whisper?

I know there's bolt work involved--perhaps too much. I've just been thinkin'.

Thanks,
jkpq45
