When I was asking some questions about another Ideal mould earlier, the subject of "Short-Cherried" moulds came up. It was explained to me that this was commonly done at the customer's request.
I can understand why Ideal/Lyman might've shortened the length by omitting a land or two, but did they ever deliberately short the length by 1/2 land?
I'm including a photo of two bullets from two different examples of Ideal/Lyman#406150 w/o attached handles. Note that the bullet on the left is shorter by ~half the width of the bottom land. The bullets are cast of ~same alloy - but the L example weighs 334gr. and the R example weighs 346gr.
This bullet is designed for .40-72 Win. and that's what I used the heavier one for - and also for an oversized .40-63 Ballard. Both cast bullets of .409"and are otherwise identical - except for the bases.
Do you think that the short mould was cut that way deliberately? If so, why?
