I do not know. Different molds and different bullet designs cast differently. Sometimes the tin bullet will cast larger (typical on a small bore bullet) other times the tin bullet will cast smaller (it sometimes happens on a big bore). Or the tin bullet might cast smaller near the bottom of the bullet and cast larger near the top of the bullet. Casting is not
a precision process. That's what sizing dies are for, IMHO.

That sounds reasonable, though most people prefer the nose to engrave slightly if it is a bolt action.
Bench rest shooters bump & size their noses. That is the only sure way to ensure a particular diameter.
Bear in mind that it is common for the nose diameter to be unintentionally "bumped up" in the lubrisizer, especially on smaller diameter bullets, though I do not anticipate that happening with 35 caliber. Or, the nose diameter may vary from one pour to the next due to lead splatter on the mold faces, etc.. Casting is not a precision process.
