I have several pre 64s and classics considering consolidating and purchasing a pre 64 super grade to be primary good weather hunting rifle. Questions

Which era? I tend to prefer early 50’s with high comb. Tell me why I am wrong.

Which caliber? Thinking 300h&h, 30-06 or 270

Don’t mind a rifle with some wear but would prefer original something I will take care of but will be hunted not a safe queen once I get it.
