I have a Remington 7oo 270 WSM I am building. So far I have the Bell & Carson Alaskan II stock and have ordered a Broughton 5C barrel, fluted, to be finished at 24” I want to make this a light rifle. I am getting too old to pack a heavy rifle around the woods anymore. I know now is the time to put in a new bolt also, so my question is how much difference will a bolt with new firing pin assembly make to the build compared to using the factory bolt? If a new bolt would be better what is the opinion of PTG bolts and which extractor should be used. Funds are limited, but I want to make this a great shooting rifle I can keep for a long time. Thanks all.
