The press is new to me, will be used to match upto my other. 1 set for large primes, 1 to be set to small primers.

But, my old press has been mounted on a strong mount for at least 20 years. I'm shocked at the prices these days, but have done some searching.

I found 2 alternatives.

Ultramount press riser system at https://inlinefabrication.com/products/ultramount-press-riser-system-for-the-dillon-550

and

a Lyman Universal Press Mount stand (it mentions the Dillon 550 down in the 'Features and Benefits' on the Amazon webpage. Sorry it wouldn't let me cut n paste.

Has anyone used either of these stands, if so what did you think?

Thanks
