Headspace and Walther KK300

[tim s]

Does headspace affect extraction and ejection in any rifle? Wouldn't weak springs or claw shape be the likely culprits? Failure to eject an unfired cartridge us due to chamber dimension, which is entirely separate to headspace in .22LR firearms with a recessed bolt face.

I 'll relay this to my club colleague who has been having the round ejection problems. It's a relief to learn that this is not an inherent issue with this rifle.

Many thanks for putting my mind at rest.

A good clean out of the extractor slots in the breech with a toothpick, and cotton buds dipped in 009 won't hurt. Many shooters are surprised at how much crud builds up in there. As Robin noted, wiping away any crud from the breech and bolt, especially from around the claws, won't hurt.
