I didn't mean to imply that a Mauser extractor would be better than the standard rimfire extractor. I was only stating that I thought it was pretty cool they were able to offer a rimfire action modeled after their centerfire actions.
I have had occasions where the standard rimfire extractor failed to extract a fired case and in the case of a Win. 52D chamber, failing to extract an unfired case because it was to tight and the extractor would skip over the rim. Recutting the hook solved that problem.
Ah, ok. I must be lucky. I don't know how many rounds are on my 1949 Winchester model 52?? It could be as few as a few thousand? It's worked flawlessly though. If the Kimber 82 is anything like the Win 320, it's a hell for stout rimfire, that I don't expect any problems out of. I will keep an eye out for a newer Kimber though. As well as a Cooper, if I can score on one on the cheap!!!
