"And of course you don't need the stripper/chargers at all. I rarely use them."
That of course depends on what you are doing with the rifle. Everyone's needs are different.
I shoot in a monthly Vintage Bolt Action Rifle match. Each stage requires 10 rounds. At least one stage is always timed. Some stages have a time limit: in other words you have two minutes to fire this stage. If you don't get your rounds off, you take misses for the shots you didn't fire.
For the last year, I have used one of my K31s. For most of the time, I used a spare magazine. In fact, I bought a second rifle just for the spare magazine because I didn't know where to get chargers for the 7.5 Swiss round. In the last couple matches I used chargers and it made a HUGE difference. It is much faster than changing magazines. And, as I mentioned before, these Swiss chargers work slick. In other rifles I have had nothing but problems using stripper clips including all my Russian rifles and my Enfields. I know someone is going to chime in and say theirs works flawlessly. All I can say is, that is my experience.
