This is my first post here, so if this topic has been addressed already please forgive me.. Last week I accidentally fired a Crow Magnum pellet backwards in my rifle. The gun is a Crosman Vantage NP. I know dry firing this gun is very bad, and although the pellet did fit snug, I hope I didn't do any serious damage. I suppose it would be like a partial dry fire since the cup of the hollow point is quite large. A couple of rounds after I made this mistake, one of the shots was VERY loud. It has become quieter since that however. I would appreciate any input. I have a very low income, and replacing the gun would be difficult for me. I did do some testing afterwards and the Crow Magnums are still expanding nicely in soap. I just don't want to invest in a scope if I have reason to believe the gun is damaged.
