I can't remember how long I've had my Partner Press. I'm leaning towards 20 years at least. I never bench mounted it as I had Rock Chucker and a Dillon already on the bench. I never intended to use it for rifle loading, or even that much handgun loading to be honest. I did buy it for, was the various reasons others have mentioned already. Decapping brass, expanding case mouths, etc. I mounted it to a board I could countersink the bolt/nuts to. I carried it where ever I wanted that way and used a pair of C clamps to mount it to a desktop, etc. It'll be staying with me, just like a good partner should.
