45 auto question

Picked some hard cast loads for my 45 Ruger American the other day. Was checking function for a few of them, they chamber fine , feed fine from the mag, just hard to eject the un shot round. Noticed it had a couple scratches to the red lipstick coating when i did get them out.
Took the barrel out and they plop right in and fall out of the cahmber just fine.
Any ideas what could be causing this, and be ok to try and shoot one?
