As the others have said: stop. Seriously, stop.
The live ammo you've been cycling is probably suspect at this point due to bullet setback: dispose of it properly, all of it. Find someone who reloads, give it to them so they can pull the bullets and dump the powder.
Clean the gun, buy new ammo, go to the range and fire the gun.
Getting some proper instruction probably wouldn't hurt either.
