Another source of high quality molds, including hollow base, is MP-Molds
https://www.mp-molds.com/ . Look here
https://www.mp-molds.com/bullet-casting-equipment/?pa_pb-bb-gc=hollow-base . They make so called Cramer style, from brass, 2 cavity and 4 cavity:
If you want solid base bullets from the same mold, just flip pins. Since points will be down and protruding, they could be easily damaged, so better options is to purchase additional flat base pins. Another possibility is to have some cavities FB, some HB, and cast both styles at the same time.
Everything mentioned about hollow base (HB) molds, works for hollow point (HP) also. Hollow point could be round style, pentagon, shallow or deep.
Of course, they make plane, solid base molds too.
One thing about MP-Molds, they make cavities by peripheral milling on CNC mill, so cavities are perfectly round. On top of that, mold could be made in various diameters; .357, .360, .362, etc, without additional cost. If you want something like that, contact them so they could make you one in a next run of the molds you want.
