Another Remington 7400 Question

Recently purchased a Remington 7400 in .270 Win. First/only day at the range I noticed that roughly half of the spent cases had a significant bend in the case neck. When mounting a scope yesterday I noticed a bit of metal protruding into the ejection port. It is in the upper right hand corner maybe 1/4" in length. Is this normal? Could this be what is bending the case neck on ejection?
I'll try to post a picture. Not sure if it will be visible.....

Can't really tell from your picture what the projection is.
Most, if not all semis will dent case necks some. Just the nature of the beast. The 7400 has a spring loaded ejector that is slamming the empty into some portion of the ejection port. There should be a brass mark on the port where the contact is. Sometimes a little judicious grinding can clear the port sometimes it is too much to remove.
Just iron the dents out of the case elks and load them!

One of the reasons I got rid of a pristine 740 (predecessor) was how bad it chewed up the brass. I am not made of factory '06 gawsh darn it.

Not sure this is your problem, but it might not hurt to check. On most bolt rifles the scope mounting screws are 2 different lengths. The longer ones go on the rear and the shorter ones on the front. It is possble to put the mounts on with the screws reversed, but when you do the longer screws protrude into the ejection port causing problems.

I'm not as familiar with the 7400 and this may not be the issue, but it is simple enough to check and fix if it is.

I have a 7400 in 280 Rem (7mm Express) and have noticed some dings in some of the brass, but I attribute that to hot ! (meaning soft) brass hitting the deck upon firing, as my rifle spits it pretty far. I check for splits after sizing and move on. I usually get 6-10 reloadings out of the brass depending on brand. Good luck ! BTW that rifle is deadly accurate, 4 into 7/8" with 150 Core Lokts (my handloads).

Remington is always having trouble with auto loaders, I passed on a sweet deal on a 742 in 30-06 because of that. Then again I had fits with my first Browning too (A-Bolt), so I guess an auto hunting rifle is just not in my foreseeable future unless I get a 6.5 Grendel AR.
