My Sons and I started reloading shot shells on the road back in the 1990's using a Mec 600 Jr.. It started one morning when we decided to go pheasant hunting, but when we woke up and realized we didn't have much loaded up for the day, I got creative and came up with a mobile loading bench. So I used an old heavy walnut cabinet amd we layed on it's side, and then mounted the Mec up. While I was driving, my Son's were in the back of the van pounding out pheasant loads. In the 2-1/2 hrs. we were on the road they managed to load up a good 10 or 12 boxes.
Since those days the caninet has evolved into a range loading bench, which is of course really cool for on site load developement for high powered rifle.
