Extraction was the short coming of the .250 Savage Marlin. I have wondered why Marlin did not look at the .25 Short Krag which is a rimmed .250 Savage. Unsticking the cartridge from its grip on the chamber wall is the key and it requires a good grip from the extractor to do the job.
The Winchester cartridge stop on the link can be raised with a punch or a welder. The .458 2" and the .450 Marlin seem to feed well.
The war between Marlin and Winchester is probably one of the biggest reasons why Winchester followed its own path.
