Do yall ever see Remington hammers that just strike the topside of the nipples, not square on? Are they designed to do that for some reason? Supposed to be that way?
If a Remington is set up properly, the hammer will never touch the nipple.
It should clear the end of the nipple by .002 to .010.
It stops on the frame of the pistol and if the nipples are of the correct height the face of the hammer will crush the cap and priming powder causing it to ignite.
If the hammer on your Remington is only hitting the upper part of the cap you might consider replacing the nipples.
The front of the Remington hammers on Piettas do hit the top edge of the nipple smashing the top. The hammer needs the angle on the front of the hammer recut so it lands square to the nipple hopefully.001 to .002 inch before it actually hits it. All part of tuning that these Italian revolvers need.
Zonie is right. The nipples on my 1858 Pietta do not have a mark on them, only the cap is hit,and to date I have never had a mis-fire after shooting it several hundred times !

"If" being the operative word here.
In my experience, the import revolvers simply are not made to tolerances where one should expect such exactitude. They all really need a tear down and several hours of stone and file work before they are fully acceptable for use. And, I don't mean a complete tune-up, just getting rid of rough edges and surfaces. Then there is the nipple/hammer thing........
On the Remingtons you will notice a shoulder on each side of the strike face of the hammer that corresponds to two seats in the frame. These stop the hammer fall so the strike face should not make contact with the nipple top.
These will batter down some(shoulder seats in the frame) after many thousands of shots and the strike face may need to be lowered some to not hit the nipple tops. MD
