Ballpark guideline: keep final lubed/gaschecked cast bullet diameter .002” -.003” over groove diameter.
Just looked at the Arsenal Molds product line up. Looks great. Many great designs, and it appears their starting diameter is good/full, but looks like they can customize diameter. Great pricing. NOE makes nice molds, but they don’t have many molds in stock ( have to wait for product runs. Uggh).I have three NOE molds. All good. But I have to admit that I think my next mold ( for a Ballard rifled Marling 1894 44 mag with a .4315” groove diameter, will be an Arsenal Mold at .434”).
Castboolits.com has a lot of good info, and good reading.
