take some light case lube and rub it on your fingers and a touch on the GC before you run it through the Lee sizer. It's going through it rough and shaving just a tad, you feel a grind when it gets crimped on? you need some lube in the die.
as for GC's, yes brand doesn't matter, Horn or Lyman. (I sell Gator checks, far cheaper BTW. PM me if interested)
the shavings won't hurt anything, they just look bad.
Somehow you need some lube in that sizing die for each of the projectiles.
