Took the gun out 15 minutes ago. Put 80 rounds through it of 158 grain, 357 mag. Last 6 rounds I shot with a target 8 inches off to the side of the gun. The gun is spitting lead. Took it to my local gunsmith at the same range, told him what was going on. He stuck a feeler gauge down the barrel and confirmed the timing is off with the same cylinders that were not locking up.
