Posted the same question on another forum as well, don't want to miss any options before I get parts. Not sure if Lyman is the only place to get a better sprue plate and will have to measure cavity centers before I order anything.
I have an old 313445 DC that i just love to shoot in the 32 H&R. The mould casts very well and for me with COWW + 2%'ish pewter drops about 80% good bullets. If I start with the mould to cool I get vent line fringes, but once hot it all goes away.
My issue, it has the very thin factory sprue plate and it stinks! It does not always leave the base of the bullet nice and flat, if I slow down it has enough flex to leave a nubbin on the bullet base. Does anyone know if a thick sprue plate is available for that mould block?
I have not been able to get it to hot, bullets do not frost. I assume it is because the cavities are tiny and the block just does not get that warm. So, one can cast very fast with this mould!
