What's the thumbrule for seating depth when you can't get close to the lands?
What's the thumbrules or guidance on bullet seating depth when you can't get close to the lands? Seems like I recall a guide line of 1/10th of the diameter or bullet length? I can't remember clearly. I have some Nosler 55 and 70 gr BT's, for the .243. They don't publish a recommended COAL for these. I doubt I'll be able to get close to the lands. Same thing happened with the Sierra 70 MK's. I seated to their recommended COAL.
