Had the same problem w/ a Savage 17 clip!! (Uh hmn... I mean magazine)
Every time I would load the clip with the bolt open, or shoot and eject the first bullet, all five bullets (Uh hmn... I mean rimfire cartridges) would fly/eject right out the clip. Extremely aggravating in the field..
I went to my local gun shop and they merely used pliers to push down the center piece of metal and close the upper side tabs on both sides. No issues since.
I also ordered two stainless steel clips for the Savage Model 93 in 17 hmr and no issues with those.
As far as the clip falling out, I only have trouble when I rest the gun right on the clip release to take a shot.
Obviously, after I would pick the gun up to eject the expended cartridge, the clip was not seated all the way. But that's me, not the gun or clip.
