Winchester 32-40 Brass Question??

[Terryrm1-03]

Got some brass for my Win 32-40 from some great guys here on this forum.
Most of the Brass are LARGE primer, a small bit were SMALL primer.
Is this NORMAL?
Next time I try to get some brass I want to make sure Large primer, and keep them the same.
Info about this would be appreciated!
Thanks TerryR

I doubt you'll experience any difference between the two primers and their ignition considering the type of powder you'll probably be using.
