I have 3 methods. I use the Phillips pellet holders on my Condors but when I use a Springer I use the Crosman pellet pouch. I don't like the velcro too much on it, only because it's noisy. But after you have taken a shot and need to open the pouch, you have already given up your position so it's no biggie. I also throw some pellets loose in the shirt pocket of my hunting shirt which is buttoned. This way they don't fall out when if I happen to bend over. The last and best thing I use is actually an old small plastic pellet holder from the early 80's. It's really a pellet tin (but plastic) and the way most Crosman pellets came in those days. It clips on your belt and stays on pretty well. A thin belt helps. Those plastic pellet containers/tins last for ever. The one I have is 28yrs old. I was just a teenager when I got it. Velcro had NOT been invented then! so the top lid just clips to the side of the box when closed. It is virtually silent if you open it slowly. The "old timers" should know what I am talking about.
I use a Beeman nylon pouch. It has a good design IMO which allows you to select whether you want to carry it open, so that you can reach straight in a grab a pellet, or closed with a piece of velcro, so pellets don't fall out when you take it off your belt.It is a simple design which uses a long belt loop. If you want it open you simply open the pouch and pull it down low on the pouch's belt loop. It stays open but is stiff enough to not be wide open for junk to fall in. I write the pellet I am using on a piece of duct tape and stick it to the pouch. That way there is no mix up.
