Rem 7400 semi-auto help

Any 7400 semi-auto experts ?? I recently bought a 30-06 in great shape. Read about the firing mis-haps with these guns - so I disassembled the entire gun (well, left in the firing pin mechanism as I couldnt knock out the dowel pin), cleaned up the barrel and everything real good. The barrel chamber seemed spotless to me - no signs of pitting at all. Put back together - went to the range 1 month later. 1st shot - jam. Gun didnt spit the fired round. Brought it home for a look. Used a cleaning rod to push out the fired brass - which came out very easily. The rim of the brass had 1 spot that was torn back. I assume this is where the extractor pulled back and ripped the rim ... since the brass wanted to stay in the chamber. Any ideas why the brass was stuck ? All I can think of is I sprayed a good amount of Rem Oil in the barrel after I 1st cleaned it - about a month before shooting it. I didnt re-clean the barrel before test firing. I really dont know what else to check - I didnt expact any problems at all ... based on the condition of the gun. Any advice is appreciated.

Were you shooting factory ammo? Auto's can be very hard on ammo that would normally work fine in a bolt gun. Next step after the chamber is dry is to try it with a round in the barrel and no clip just to rule out clip issues.

Sounds like ammo wasn't sized properly. If you are not sure of your ammo, go buy a box of factory rounds. Jeff

You have an issue if you wre shooting factory ammo. I know what he is saying about too much lube as I have seen brass do that when reloading but I have never seen it cause a gun to fail to eject. It could happen but few of us leave a gun that wet.Jeff

My theory is that you will have the same problem after you dry teh chamber. In fact I bet the chamber is dry already. Jeff
