I am modifying another breech block for 7.62x54R. The one I had been using is missing. So I have a couple of questions.



I modified the internal radius of the extractor or whatever you call the part where the rim fits in the extractor.



The extractor in the 54R bolt is sticking up in the picture. ( The DP .303 bolt is for comparison. ) Does it matter that the extractor is like that?

Also, when I am done modifying the breech block will I still be able to shoot .303 with it?
