I haven't tried to load any European brass, so haven't run into that.

If you can't find .309 bullets to use, it would be easy to get a Lee .309 sizer die and run the .311 or .312 bullets through it. I have resized .311 rifle bullets down to .308 and .338 down to .329. I use Imperial case sizing wax or maybe a little Tetra grease and everything works out fine.
