I shoot just one rifle and 2 handguns. Wife shoots just one rifle and one handgun. Handguns are carried in holsters on the cartridge belt, so that leaves just a rifle for each of us to carry, plus the range bag with the ammo in it which CAN be a bit heavy, but we manage. Our shooting range is at the bottom of a steep hill. No problem carrying the gear DOWN the hill, but after shooting all of the stages, packing everything back up the hill can be a bit of a challenge. Yes, a gun cart would be nice, but pushing a cart UP that hill wouldn't be easy either.
Several shooters in our group DO use a gun cart and nobody complains. Without the cart, those folks might just have to give up and not participate. We need everybody that wants to show up. If a gun cart makes it easier for you, then come on down.
