I do not recall ever seeing it mentioned here. This gadget is a Score High benchrest follower. It's a little gadget that fits in the magazine box and allow you to load one round at a time much more easily than through the magazine.
I use one in my M77-UM and it makes loading my very long cartridges a snap.

Scroll down. Boyds has them on sale for $6, and Midway carries only one model. It's easy to install and comes right out if you need to use the magazine.
For load development or prone slow fire competition, this gadget is excellent.
