For the most part, there is basically standard, e.g., .308; magnum; and .223/5.56 bolt faces. Actions also come long and short. For example, .308 Winchester and 30/06 Springfield both have the same standard bolt face, .308 usually uses a short action while 30/06 uses a long action.
So, your .243 Win., 6.5 CM. .308 Win., .35 Whelen, etc. will all use .308/standard bolt face.
