Was always a firm user of Remington but thought I would try to save a couple of bucks and try this Kent Fasteel stuff. I picked up a box of 3 1/2 inch BBB in 1 3/8 ounce. I think they go about 1550 fps. Does anyone else use these type shells and how do you find they perform on geese. I also picked up a box of 3 inch BB also in 1 3/8 for the girlfriend to use. Should be as good as any Remingtons out there? Another quick question can you get Challenger shells in the U.S. and has anyone used those.
