The face of the breechblock is flat. If the extractor were moved back a little the bullet would sit flat. When I push the bullet flat to the breechblock the extractor rides up a little on the back of the groove in the cartridge.
I did remove the striker, and performed the same test with Winchester 115gr bullets. The action performed perfectly when cycled quickly by hand.
I will be out of town until Saturday and may not have computer access. My Mecgar mags should be waiting for me when I get home.
