[QUOTE="Etienne de Beer, post: 1679406, member: 110777"] I would like to know whether it is an option to change a Remington 300 WM into a 300 Norma Magnum Improved. There seems to be a lot of controversy regarding this. Some people say it's fine, some say it isn't. As far as I understand, the increase in cartridge base size means that the bolt face need to be opened and a Sako type extractor need to be installed. This does not really worry me and if it would improve matters one can always install an oversized PTG bolt as far as I understand. The main issue seems to be the increase in bolt thrust which might cause bolt setback and possibly safety concerns. Would "improving" the 300 Norma Magnum lessen the amount of bolt thrust because of the change in the shoulder angle and also possibly less tapered case? Is bolt setback really a concern? I would really like some information, not only for my own build but also for other guys contemplating doing this. [/QUOTE]
