Worked in a gun shop a bunch of years ago. We had 5 boxes of 358 norma ammo on the shelf. Started doing a little reading about the caliber and thought that looks cool. Bought the ammo and started working on a rifle build around it. Built that one about 30 years ago and have done similar things since. You can see where that kind of thinking has me on a gun forum!
Uuuuummmmmm ... that sounds just like someone I know!
