Just wondering what everyone thinks of Jim Clark's double rifle conversions? These conversions are done on CZ SxS shotgun actions. Originally he just offered a 405 Winchester, but now you can go as big as a 500 NE. Here is a link to his site http://www.clarkcustomguns.com/DblRifle.html. Here also is a link to a video on Guns & Gear with Tom Gresham were they are shooting the double http://www.guntalk.tv/gtv/library.php?category=54&video_id= 396. Jim states he handloaded the 405 Winchester with a 400gr bullet at 2150fps; the Hodgdon Manual lists Max. at 1945fps. What do you think?
