Trying to get some info for a friend to help him get started shooting. I reload for several calibers and dabble in prs style shooting but never really messed with a 30-06. He tells me it's a seventies Remington 700bdl. How would he go about finding more about it. Like what twist rate and what kind of ammo to start with shooting longer ranges? I don't know if there's a standard go to factory round for 30-06 like the federal gold medal match is for 308. I'm familiar with the cleaning rod method of checking rifling but I thought I'd check here first to see if maybe it was an easy answer. Thanks.
