I had never even heard of 5R until a short time ago and now it's all the rage. I have the 10FCP-SR and I love it. Sub MOA right out of the box and I've never had a problem with the Savage mags. If you learn how to insert them you won't have an issue with them dropping. I can load it with a full ten rounds but I choose to download it and all of my mags by one round.
