[QUOTE="J E Custom, post: 705261, member: 2736"] When you open a Remington bolt face up more than .540 it doesen't leave much. and the extractor needs to be thinned making it weak. I personally don't like to open up a remington beyond .545 for any reason and the PT&G bolts are good but they are the same size. I know they do it, but when you increase the bolt face Diameter you increase the bolt loading, and exceed the original design loading. This can cause recoil lug set back with heavy loads. Also if you load longer than the magazine length you must load it like a single shot. I build all of the big cases on Weather mark 5 actions if a factory action is used because of bolt dia. and mag length. J E CUSTOM [/QUOTE]
