does anyone shoot cast bullets from their AR period?  what kind of results?
anyone shooting them from a CHF barrel? what kind of results?  
anything on either to think about, watch if going to try it?

Cast bullets can't be driven to the speeds needed to cycle the gun, so plan on your AR being a bolt action. I can't comment on whether the bare lead will cause any problems with the gas system - probably not as its not much different from running a .22LR conversion unit.

that extra 2k fps or so will lead up a lot quicker if you run 223 velocities.

I was thinking of doing this in an autolaoder (not AR) but gas checking the little pills of happiness

Loads should be able to be developed that would easily cycle the action.  Velocities of the bullets aren't the thing, port pressure is.

Having said that, developing a load tailored to make te rifle a straight pull would be a great idea for small game shooting allowing you to save the cases.

The gas port is always a factor in cast bullet shooting in a auto rifle, and you may find the bore between the gas port and the muzzle leads faster than the rest of the barrel.

In addition, the 1/7 twist of many rifles is no good on lead bullets.  1/9 is better, but the original 1/12 is perfect.

There is also the potential that leading of the gas tube could cause diminishment of the ID of the tube.

Would be a fun project.

I shoot lead cast 9mm 147 grain bullets out of my AR. Haven't noticed any fouling but I do shoot hanfull of copper jackets after. If that means anything.
