I carry everything but extra powder, bullets, and caps in my hunting pouch. I try to keep the loading procedure the same as it would be in a hunting situation, with a few exceptions like keeping the cleaning jag on the ramrod and laying it on the bench between shots.
By the time the shooting session ends I usually have an empty pouch and a bench covered with equipment.

I had to start picking out what bullets I wanted to play with ahead of time or get wheels for mine. Lee

There ya go!!! Isn't that was extra cabs are for? Tool box, hold down straps, shooting bags, boxes of bullets, ML Dry box, rain gear. It all fits in the back seat!!! Chap

I use about the same setup... The big flat fishing lure/worm boxes (for tools, jags nipples, breechplugs, etc..50cents @ garagesale.A smaller waterproof softpack cooler($6walmart) w/extra zippered comp.for powders/measures, caps,patches etc. and a cheap canvas tool tote for range use. Then larger airtight rubbermaid storage boxes for home. I take a small camo fannypack with whatever I need when I go to the woods. LOL I guess I'm just as bad (or good) as everyone else about packing/storage. But it'll pay off in the end. I even keep a small carboard checklist on the inside window of my fannypack. One time I got to the property where I hunt. (Walked!) And I didn't have my powder measure!!! I used the plastic cap off some spray scent and eyeballed my measurement.... image that.

This is what i use. It is from Cheaper Than Dirt and is called an "ammo can organizer." i carry my bigger stuff to the range in a haversack. Yep, my foot got into the photo.

Everyone keeps leaving out one important range item - an ice chest for drinks and lunch!

I use an MTM Muzzleloader Dry Box. Works great for me. Holds a lot of Stuff.
