The original 1903 stripper clips aren't very strong. They rely on small tabs on the bottom to retain the rounds, which tend to snap off with just a couple repeated uses. They were designed to be one-time-use items. They can also be tougher to find, simply due to the fact that the wear out easily.
A more robust and more readily available option is Swedish Mauser stripper clips. They function just fine in 1903s and 1917s, and hold up much better to repeated reuse. It's what I use for my USGI bolt guns.
You used to be able to get a 40 pack for like $5, just a few years ago. Nowadays, it seems like $1-$2 each is the going rate.
