Admittedly this isn't going to help me in the field much but I just thought it was super cool and like most of us I have a regular job and a desk so I like discrete hunting/fishing related office stuff.
So, to the point.... I was ordering up a new jet foot the other day from Glen at Wooldridge boats and he mentioned that he had picked up some pretty slick custom pens made from a 30-06 and a 308 case. As a guy who hunts/fishes/boats and works for a California based company that is 99% my polar opposite I had to have one!
Right now it is living with the reloading journal but will definitely be making some business trips! That is if I can keep it away the wife who has a thing for great writing unique pens and the cross internals make it much more than just a show piece.
