The 210gr 303 bullets I sold were from a 5-cav NOE 314299 gas check mold. It's a good bullet for 7.62x54 and .303. I had sizers for .312, .313, and .314.
I ladled everything. I used 2x Lee Magnum melters - one that I cast from, another to melt alloy at the same time so I didn't have to wait between pots. Lee says these are 20lb capacity but in reality it's about 15lb max. I had 3 of these pots actually, 2 in use and one for back up. The heat element wears out over time but is only about $15 for a new element. I changed 4-5 elements in 6 years.
