I'm at a loss. I've got a model 70 7mm rem mag, post 64, 2001 to be exact. When loading the first cartridge into the blind mag. It pops right back out most of the time. If I hold it to load a second and third round in, then cycle them, sometimes once down to one in the mag it pops out. Only with one in the mag does this happen. Not sure where to go with this.
