What is stripper clips?

Stripper clips are devices used to quickly and easily load ammunition into a firearm. They are typically metal strips with indentations that hold individual rounds of ammunition in place. The rounds are placed in the clip in a specific order and can be inserted into the firearm's magazine in one swift motion, allowing for faster reloading. Stripper clips are commonly used with rifles, particularly military rifles, and were a popular loading method during World War I and World War II. While stripper clips are less commonly used today due to the prevalence of detachable box magazines, they are still utilized in some firearms and by shooting enthusiasts.
