Remember the .50BMG bottle opener? Here’s one for the C&R rifle fans, a member over on Reddit made an awesome bottle cap opener from a spent steel 7.62x54R casing.
I didn’t expect this post to get as big as it did! Some information about the bottle openers. I cut them using a triangle jewelers hand file and a drill, then sanded down the outside using 100 grit, then 220 grit sandpaper. I’ve done a good amount of testing with these. That is to say, I drink a lot and it hasn’t let me down yet!
These aren’t for sale from the member who made them, but they might be in the future. Or you can give it a try and make your own if you have a few spent casings laying around.
