I got these, they had a sale and I figured I'd want enough to fully load it. Discovered a few interesting things. Action will not load a fresh round unless trigger was pulled, or little lever on bottom of stock is tripped. Administrative unload requires a firm push, as it raises the stop when you push, and thumbnails are at risk when the round ejects.
