Mike,
That's not the way I'd do it.
As far as I'm aware them terminals are only designed for one solid wire.
One the same side of the coin, stranded wires (as used in patch leads) won't work either.
I was part of a building renovation a couple of years ago and the "phone tech" was there working on the Comms panel, I noticed he was pushing the wires into the 110 blocks with a terminal screwdiver, I asked him if he had a proper punch-down tool.
"Yeah, but it's out in the van, I'm in here".
Unreal.
