I was shooting my new to me lrpv 223 this morning. got it sighted in using factory lapua ammo with no issues . I chambered a reload to shoot and tried to eject the spent case , but could not get the bolt to pull back. the bolt lifts fine, just can't get the bolt to move rearward. I have shot this load many times out of other rifles with no issues and am not at max, but I will double check.

What can I do to get this case out ?
