Argo44,
Since you are a muzzleloader as well as a cartridge guy, you might like a cart like this. It has a tray up high where you can put reloading/cleaning supplies, score card, etc. I use this for long range muzzleloading and Creedmoor BPTR.
Rifles ride muzzle up, but more vertically than in the baby jog carts. Big wheels are a must for unpaved ground. Being able to hold a rifle horizontally is advantageous for breechloading rifles. Probably not a big thing for shotguns though.
It also collapses, and the wheels come off with lynch pins.
the space in front of the rifles is used with a fitted wooden box that serves to haul ammo (165 rounds in my case) and other supplies and lunch. It serves as a pretty decent stool too.
