If you feel you need to size that bullet use the Star sizer. The star sizer you can adjust the sizer so you can push the bullet through nose first and still put lube on the bullet. The nose will never be damaged pushing it through nose first. You can use a flat top punch or one that fits the nose either way it will work. without nose or base damaged.
It's always best to get a custom mould made that fits your bore and groove and pan or dip lube that bullet. It's best to get a proper bullet size than pushing it through a die to reduce the diameter and displacing the lead. You can't compress lead you can make it flow to a lesser space and that bullet will be a lesser diameter but still be out of balance.
