I'm using their large pistol primers for the last 7 years or so, never had a FTF, my springs are not the super zoomy kind.
I uniformed my primer pockets, with a specific brand of brass I had high primers
...... and overhere they're the cheapest ;-)
My sizing die is reamed to .472 and I use a .452 inside reamer for my home brew 45 CS.
I made them from Starline and Magtech brass and only the starline brass needed inside reaming.
