Is this brass now trash?

[the great orator]

   I have been using my once fired brass in a friend's rossi single shot (.243) to try to work up an accurate load for it. (which is a whole nother story)
  I full length resized the cases, trimmed them all to length, and loaded them again, to use with my Stevens 200. 

  Upon hitting the range, I could not chamber most of the rounds, to which I thought that I had loaded the bullets out too far. 
  When I got back home, I was looking at my brass against factory brass and noticed that the shoulders appear to be different, almost at a less dramatic angle, and possible going up farther than the original brass. 

 My question is, is this brass now relegated to using in the Rossi only, or can it be resized back to size?  (I never lube the shoulders as I found out early on that if I do, I end up crushing a decent dent into the shoulder)

  If you have this AFTER full length resizing, then yes, it is only good in the Rossi. I'd only keep those rounds,or cases that did fit your gun. Give the others to the guy with the Rossi. OR toss them in to YOUR recycling can. When you get it full turn them in for scrap and buy more reloading stuff with the $$.Don't dump these on some one else, they will get angry and give YOU a bad name.

You could probably full length size them to fit in your rifle again; if it were my brass and my rifle, I would at least try it.

You can pull the bullets and resize the brass.

Sounds like you don't have the dies set to push the shoulder back enuff. you can do it but they would probably chamber great in the rossi.
