Ed Harris' article on "Silent But Deadly - Part III"

Actually, I believe I first read of this project on another page, but didn't bookmark it so can't locate it right now.

I definitely appreciate all the input. I'll have to see what turns up this summer while we're up north. It seems that this would be a really fun project. Further email conversations have lead to further information. If I understood correctly, Ed Harris chambered it originally to 32 SWL and gave it essentially a 7.62X39 style throat. He also states that the government 30 caliber 4 groove barrel with 1:10" twist works fine with common .32 handgun ammo and will stabilize Ball M2 or M80 pulls subsonic for use with a can using a compressed case full of IMR4198. That last should get some of you to perking up your ears.

If any of you get a wild hair and decide to build such a critter, I'd love to hear about it!

Thanks again!
