Both ~251 grains with my alloy (3:1 lead:lino + tin).
The Ideal mold (2-cavity iron) drops at .433", the Lyman (4-cavity iron) dropping at .430".
Both relatively the same length. The Ideal has a very slightly wider meplat.
Base band is thicker on the Lyman.
The Lyman has the square grease groove and a very nice angled crimp groove. The Ideal has the rounded grease groove and no angled shoulder on the crimp groove. Not sure how well this will show up with my cell pics.
