The more you shoot, the more you have to carry to the range.

The more there is to carry, the heavier it becomes.

The heavier it is, the sooner you realise that you're not so young as you used to be, and walking around the range all day from stage to stage lugging gear over shoulder makes tired old muscles sore.

I started out with a duffel bag, moved on to a knapsack, then a shopping bag on wheels. The wheeled bag worked ok, but it was a bit flimsy, and the weight of the catridges hauled over rough ground was loosening all the joints on it.

I needed a robust version of the wheeled bag that

• could carry all my gear

• be easy to pull over rough ground

• double as a chair between stages

• fit into the trunk of my car

Here's one way of doing it, and an idea of how to put one together yourself.
