Have owned several handi-rifles, recently purchased one in 500 S&W. Apart from disappointment in that there is no longer an ejector, just an extractor, was happy with it.
Today was first really nice day to go shoot. After 15 or so rounds fired among various shooters, the action opened upon firing from the bench. I thought that it had not latched properly before firing, and the round impacted the target at point of aim. No stress marks to the case or primer, etc. Seemed like it opened instantly upon firing, but the pressure had to have dropped first. Fired up the video camera, made absolutely sure the action was locked tight and fired again, and again it opened, this time on film. Again, the bullet hit the target, and the case looked normal. Needless to say, we quit shooting.
The rounds fired were standard Hornady handgun rounds. Anyone else have anything like this happen? I can't unlock the action without pushing the button, but the release button has always had a lot of slack in it, and it rattles a little. My other ones weren't like that. Getting ready to send it back.
