Okay, first off. Go over to CASTBOOLITS forum and do some reading. A wealth of knowledge and great people there.

Now, from experience I will tell you it can be done very well. I am using h4198 in a 16 inch dpms upper, 223 chamber- 1-9 twist- free float tube- with a mid length gas port, and have no problem with reliability issues. It will lock the bolt back every time. I run about 17.5 with a 59 (as cast, checked, and lubed) grain flat point RCBS boolit. It will shoot nice 1 inch groups at 50 yards, and while not running at 2700 fps, it is cheap to load and I never have to look for bullets. I can load them for less than .09 per round. And I get 400 per pound of powder. H335 was real nice too, but I ran out. I may try 3031 as well.

The bore is clean and shiny , and no it's not the lead I see, after each use. The gas system is not full of lead either. I understand the port pressure in an AR is approx. 15,000 psi. How much do you think stays in there? The bolt is no dirtier than with regular rounds. And I think your barrel life is a bit longer running mid range lead boolits as apposed to full house copper condoms.

So I say try it. Read about it first, but it can be done. Even if the internet tells you otherwise. I never saw the internet firing lead boolits anyway!

With respect, I am suspicious of your $0.09/round figure.  If it's easy and accurate enough, saving anything makes it worthy.  But I can't make a powder puff .38spl LSWC with 2gr of TrailBoss for that cheap and .223 takes a lot more powder compared to pistol.

Okay, cost per round,,,,

Powder at 22.95 per pound  is .0032785 per grain x 17.5 = .05737

Gas checks  25.00 per 1000 = .025

Primers at 25.95 per 1000 = .02595

your right,,,, .10832 per round,,,,, 10.83 a hundred .     Nine cents a round is off!

A bit lower than factory heads.   I know where is the lead. I have never bought lead, I harvest the range berms always.
