So I just dropped in a factory loaded 45acp into the barrel and it seems to rattle. Doesn't look tight and I think gas could escape back as colinjw mentioned (unable to expand enough to seal the chamber). Being new to the 1911 could someone tell me if the cartridge should be snug or should there be some 'room to rattle' when placed into the barrel?

yes, in 1911 pistols an unfired chambered round must have room to lightly rattle
Are you seating and crimping your bullets in the same step? That could be an issue as well...
I've noticed that sometimes the case length affects the strength of the crimp, and a improperly crimped load will not generate enough pressure to allow complete burning of the powder -> more crap all over the place.
Tray seating the bullets and crimping in seperate steps... hopefully that solves it for ya

"You are experiencing classic blowby. It is caused because the powder charge does not develop enough pressure to completely obdurate the case enough to seal it in the chamber. So some of the gas escapes around the side of the case, staining it in the process. It happens only on one side because of gravity. It is normal that a round fits in the chamber with a tiny bit of clearance. When the round is fired, the case is sitting 'down' in the chamber. There is more space at the top, so that is where the majority of the gas escapes.
The classic way to get rid of blowby is to raise pressure, to seal the case better in the chamber. You do this by either going to a heavier bullet, or adding powder. However, you don't have very far to go with that load before you reach the maximum recommended load. "

Thanks for the replys guys...
I was at the range today and using commercial ammo had the same problem. Had cases that were filthy on one side but noticed that I didnt have crap hitting my hand atleast. A gentleman at the range pointed out that the ejected cases were oval and said it is definately a chamber issue (misformed?) in his opinion.
Should I be upset at the CGNer who I bought this from. I find it hard to believe that he would not have noticed this?! Maybe the reason he passed it on???
Anyway, what are my options? Would a new barrel solve the issue? I don't think its a safety issue but it bugs me... Thanks again for the reply's...
