Based on a very limited sample, I have noticed the following regards to cartridge feeding reliability in some M96 and 98 Mauser rifles. It seems that so long as the extractor doesn't bind in any way on the cartridge head, chambering reliability may be controllable to some extent by bolt cycling speed. I noticed this at the range bench with some rifles with more than 1 cartridge in the magazine. When slow cycling the bolt I would get bullet noses jamming against the barrel shank even when COL to spec. Under the same conditions, but cycling the bolt forward as fast as possible, the cartridge would align, feed and chamber correctly. I just may have missed some basic truth about these rifles so am looking to the broader and deeper experience in this forum for further information regards to cycling speed. I know cartridge feeding problems in Mausers can be very complex.
