Yeah, I see that everybody has his own requirement and opinion. Everything is worth being respected

I (stubbornly) stick with my pouch, less hindrance and dryer loins.

A drawback of the pouch is the balance : as I am over 50 I have to be careful. If my belt (thin canevas army belt)is not well balanced my hauches will cry within 2-3 hours. On my belt I am wearing a camera on the right, a video cam on the left and my ammo pouch centered on my back. If there is more weight on one side, sure a hauch will protest.
I must add that I am using a 375 rifle fitted with a magasin. So 4 cartridges in the magasin and one in the spout. I bring another magasin in my breast pocket. That enables me to shoot (theoritically) 9 rounds in no time.

As You can see there is no place for an ammo belt.
