I have two of them. One is a 4-cavity plain base. The other a a 4 cavity "dual" mold ( 2 gas checked and two plain base.). I bought them for my Marlin 1894 (Ballard rifling) 44 mag, which had a .431" groove diameter.
Sold the Marlin ( actually swapped it for an 8 hp Yamaha 4-stroke outboard.). Still have the molds ( and Saeco 0.433" sizing die) .
The NOE mold produced a nice bullet which shot well in the Marlin.
