in short, Yes.
Remove the pin, if you intend to resize them (best practice).
If you don't intend to resize them (which I have done in the past), don't take the pin out.
I used Remington Pre-primed brass for sometime, and only had a few issues in 400 rounds where I needed to resize the case - because it was slightly out of round.
From experience though, I can tell you that you may need to expand/ bell the case mouths on them - some of them are a little tight when it comes time to seat them, and of course, by then, you've already added your powder to the case...
