I don't know what round/s you shoot but for my 338 Lapua based round I use "A couple of these pocket cases from Sinclair".
They won't work very well for smaller cases, but for the larger cases they work great. I can open one up, lay it on the ground etc. when shooting and the rounds are always clean and handy.
My sling has holders for 4 rounds and since I hunt a lot with vests or coats of one kind or another, my wife has modified the slip on cuff type holders by cutting them in half, keeping the elastic pouch part, seals the edge with her serger and then she sews them inside one or two of the bigger pockets on the vests or coat. That way they are secure, covered and yet readily available. Loose shells that rattle drive me crazy and I'm also anal about protecting the bullet tips so every round has a nice secure spot somewhere.
