I noticed you stated this is a "used" Rem..... did the owner before you disclose any ejection issues to you (I strongly doubt if there was anything said if there were any issues)? The bolt also looks like it has a low round count through it... as wondered by not only me... if that bolt had an issue to begin with too.... If you can remember: How far was your cases gettin launched when they were getting ejected and how hard was it to get the bolt back before this happened?
