You can still load from the feed lips. I like the idea of having a stripper clip (if that's what they are calling it) on standby. As with anything it takes a little practice to be quick at it.
Although I haven't tried it, it seems like one could reload using the stripper clip without even removing the magazine from the rifle...if the clip clears the stock when it's inserted. Might be pretty akward trying to do so.
Thanks the video did help, I have noticed I have to be real careful to make sure the shells are all allined right. especially the last five in the 25. Here is another video that tells a little more about it. http://www.youtube.com/watch?v=z431UT7_-YU
