Hot take: I think hand ramming is better than jolt squeeze for small job molds

I worked at a place in Toledo for 3 years where they swore by jolt squeeze machines for everything, even tiny 2 part molds. Then I joined a smaller shop that does mostly custom work by hand. I can tell you right now those jolt machines leave a soft bottom every time if you don't pack the drag properly. But hand ramming gives you way more control over density and you can feel when the sand is right. The old timers here say jolt squeeze is only good for production runs over 500 pieces. So which is it guys, am I crazy for thinking hand ramming gives a better finish on small batches or is the machine really faster if you know what you're doing?
