DO NOT Shoot cast bullets in a Dan Wesson Ported barrel. There is a gap there between the ports and barrel that will clog and while it makes no difference in the shooting you'll play hell getting the shroud off later. The issue begins with the fact that the ports in the barrel and ports in the shroud are not lined up, the serious relief gap makes the problem worse, the only good news is that if you are not successful in removing the shroud just send it off the DW and they will get it done for you. I was able to get mine off by shear luck and force applied with tons of penetrating oil. Can't remember which barrel you actually have on there? Pull the damn collar and look.
For the rest of the ported guns out there of good quality, shoot away.
