A long time ago we used to go hunting with a pocket full of shotgun shells and a hand me down vest and knife. Low brass was common place and high brass express and baby magnums were pure gold. We had never seen the 3" magnums but knew they were made somewhere when we looked at the Remington catalog in 5th grade. Back then you had to change the barrel to change chokes. Funny how now I run through 3" magnums during waterfowl season like skeet loads and my game bag ain't getting any heavier.
