Forgive my ignorance, but is SAE 30 ND different than what I have pictured ?SAE 30 weight ND is the only oil I use on any moving parts that slide or rotate. It is engineered to STAY in place. If you reload PB cartridges, use it on your press‘s ram and linkage. When I read my Dillon manual years ago it stipulated to use ND30W oil and darned if those guys know what works best.
