Any chance of a picture of the damaged brass?

I take it this is when loading?

The way to load the falling block Sharps is.....

Half cock the hammer..... Drop the block to expose the chamber..... Insert cartridge...... Raise the block...... Full cock, sight and fire.

It's having the hammer down on the firing pin whilst loading that causes it to drag the pin across the base of the case whilst closing the block.

I scored probably around 200 cases before finding this method buried in a book about buffalo hunting some 80 years old....!!

^^^^^ what he says

the block is only opened and closed on half cock, its not my first sharps
its not gouging just shaving a tiny piece

Sharpe leading edge and poor tolerances...

thats what i thought but i have stoned every edge, i did ten in a row and found shavings on the tip of the firing pin i have moved the pin in and out to no better effect it has me stumped

firing pin too long or too much protrusion ?

Have you tried chambering and closing the block with the firing pin removed?

I am with SimG on this, all I can think of is the block is catching the case head slightly on the up stroke. Have you tried it with the firing pin removed?
