I would think a fast lock time would be an advantage anytime you shoot longrange without a real solid rest and make less of a difference at the bench or in short distances. I just remember Remington was considerably faster than a Winchester. I was just wondering what actions were being used now for long range shooting if the Remington had real problems with the extractor mechanism. In googling, looking for the Remington problem there seems to be some controversy whether there is an extractor problem or not. I do see some smiths offering to convert Remingtons to Sako extractors. It is just something I was never aware of.
