A while back I picked up a custom built Remington rolling block in 30-40 Krag. I assume the action is a No. 1, so I am keeping pressures low. I have no idea who built it or when. The problem has to do with extracting cases. Even new brass that easily slides in and out of the chamber is not removed by the extractor. It appears that the extractor is not tall enough to engage the case rim. I can think of several ways to correct this, but was looking for suggestions since I am no expert with rolling blocks. An easy solution is preferred since I am not a machinist. The extractor is just a nub of metal on the block (circled in red).
