Forster. - - Hand's down. End of discussion. No debate. ;-)
When I see that I have to chuckle.
Have you tried a Off the shoulder trimmer? Chamfer and deburr as well.
I can process 300+ rounds in 30 minutes.
So no, its not hands down, it may be a choice.
Having used both and having worked with tools all my life for a living, I can tell you good from poor, ok from bad.
Its not that hand cranks are bad or don't work, they are just out of date.
A bit like sticking with corded drills when there cordless are out there.
I do own a corded drill and I do use it (not a case trimmer driver for the most part)
I also was one of the first to adapt a cordless. Why? Because I could do a job that I was having to hand crank hex bolts in. You could not stink a corded drill around without endless snagging.
We don't hand crank our cars anymore, someone figured out that was a tedious and rough way to go.
And yes I do use the hand trimmer, I had 40 rounds of 270 to trim that is a hunting rifle.
It did it fine, but I can tell you, its sure is nothing like the Tri Trimmer and corded drill driving it. If I go to shooting much more of that 270 caliber, Tri Trimmer it is.
