[QUOTE="jvarga, post: 21060, member: 174"] Does anyone know if the factory 338 chamber has sufficient headspace to use the extra 1/10" of a full length 300 or 375 case? Assuming one lengthened the chamber (and didn't use the magazine), would 2900+ fps from a 300 gr. MK be possible? Appreciate any info. Thanks, Joe [/QUOTE]
