I don't think bore-drop alone is going to solve the problem. Here's why.

The paint that gets pinched (2nd ball in the stack) is getting CRUSHED between the unmoving snub* and the moving slide and its attached feed block.

• To completely eliminate the possibility of that crushed second ball, the gap between slide and feed block would have to be eliminated.
  
• That means removing the feed block, possibly milling the slide and attaching the feed tube directly, without a block.
  
• A bore-drop conversion helps guns without a moving slide because the only "gap" where a ball can pinch is between the bolt and the unmoving snub.
  
• In a gun like the DD68 Redux, converting to bore-drop would only eliminate a small amount of the gap, leaving the slide and block to pinch paint against the snub.

* the term "snub" refers to the "body" of the gun

Glad to hear you have not totally abandoned the "Bore Drop Insert" idea

I like the look of the bolt howzabout a photo of the insert

I think a bore drop conversion will make pinching worse unfortunately. Although it depends on exactly WHERE the ball will be dropping (on the larger part of the bolt or smaller part), because consequently the snub will have to be thicker or thinner.

Bumping this thread after a eureka moment.

FYI, both DSA and Dukie came up with this idea independent of each other.
