Recently obtained a Saeco RG4 aka Saeco #301. The holes in the sprue plate seemed very small and when measured were both .100”. Casting is difficult; getting both cavities to fill out is tough. But when cutting the sprue there is almost no resistance and the bases are beautiful. Getting the rest of the bullet to fill out is hit and miss. I have a newer Saeco #315 mold that has sprue plate holes that are .152”. This mold casts easily and fills out the multiple grooves well. The#315 is accurate, bases look good but are covered with gas checks just like the #301. I’m considering opening the sprue plate holes on the mold to .152”.
Any thoughts pro or con?
