Boolits? Or bullets?
I had a Lyman 429422. It is a Keith design of the 429421.
Casting was a slow process as it is a single mold. There were lots of rejects.
The specs suggest a 225 grain bullet, but mine were running 215 as the mix was harder.
Used them for a time for Silhouette and eventually bought a similar commercial lead bullet that weighed 245.
