Merkel Rear Trigger Problem I hope someone has a solution to this problem…

Subject: Merkel 140AE double rifle. I posted in the more frequented shotgun forum since this is a trigger problem.

Problem: Double trigger boxlock ejector Merkel 140 AE rear trigger increases from 6 pounds to almost 12 pounds after a few shots. I fire this gun by alternating the barrels right to left. On my 16th shot (attempt) I could not pull the trigger.

I took the gun to my gunsmith who disassembled it and set the triggers to 4 and 6 pounds.
Next time shooting with less than another 15 rounds, the rear trigger suddenly increased to almost 12 pounds.

Back to the gunsmith who disassembled and inspected it for a possible cause to include possibly the stock binding. He could not find anything.
Reassembled and return to range. Once again after relatively few shots fired from each barrel, the rear trigger suddenly increased to almost 12 pounds.

Has anyone seen this problem before in any boxlock rifle or shotgun?
