We have some black powder enthusiast among are ranks.  We were basically trying to replicate a 20" Gov't profile.

To fire, the powder charge and bullet are loaded via a ramrod.  Using a standard magazine with a single shot follower, an unloaded  5.56 case is loaded into the mag, inserted in magazine well and loaded just like a standard rifle.  


Once the rifle is fired, the empty brass is ejected manually and then reloaded.  



Here is a quick demo vid...

We tested it with 6 pellets and 2 bullets(and a very very long string) and it held together just fine.  Now it is off to MP test.

It is a modified .223 case that uses a 209 primer.

Quoted: that's pretty neat.  just make sure you clean the hell outta everything!!!

Everything is Nitro Coated.  It should be impervious to corrosion.

Tromix did it quite awhile ago...

Click on the "tromix project" link on the left side, glad someone is doing these on a regular basis...

How do these shoot compared to a regular ML with the usual 28 inch barrel for accuracy?
