I generally agree, tho with the condition my rifle exhibits, a slow load {not a short stroke} can result in the cartridge hopping in front of the extractor which of course cannot snap over the rim when normal bolt thrust is used and must be pinched at the middle to allow this to occur. At some point I'll get around to fixing it.

A replacement extractor that does not have the large undercut, i.e. bottom cut away would be best I believe.
