Default Rossi .270 single shot action won't open

I need help in fixing my rifle. It's a Rossi model M12270. I've had it for a couple years now and it's always worked fine. Last season i was using it hunting deer and it wouldn't open afterwards. The action opened twice on me after shooting it. Didn't think anything about as i figured i had done it on accident while trying to reload the rifle. It did the exact sam thing a third time and wouldn't open after i closed the action. Can anyone help me figure out what may be wrong with it?

Thank you and have a great day!

The pop open issue can be caused by an improperly fitted barrel or the action isn't closed completely after loading, or oil on the locking surfaces. One cause for the action not opening is the firing pin is stuck in the primer, you may be able to move the firing pin to the rear with a knife tip or screwdriver enough to open the action, it could be caused by excess head space or too hot a load/bad chamber/excess head space binding the action up.

Not sure of the cause but getting one unstuck can be done by driving the hinge pin through the receiver. Then you can just remove the barrel. It will take a large cup face punch ( about 5/16 size), a padded vice and a two pound hammer.

My Rossi hinge pin is splinned on the right so drive from left to right if yours is the same. Takes one heck of a whack to get it started.

Be careful to keep the punch on the pin and not on the side of the receiver. Pin can be driven back after barrel is removed.

I didn't ever have any issues with the firing pin punching into primers. I've seriously thought about letting a friend of mine take it to the machine shop he works at to fix it for me because i have NO experience with working on guns

I had a friend with a break action rifle (double barrel) and he had an issue with cratering - the firing pin hole was slightly too large (or firing pin slightly too small?) and the primer cup would flow into the firing pile hole, thus stopping the action from opening normally. He was able to belt the thing open with the palm of his hand, shearing off the small primer cratering extrusions.
