Redding The Boss a bit wobling

[RTTY]

Hello gentlemen,
I noticed that my Redding The Boss have some wobling when the ram are up.

I can't figure how I can measures the shifting of the ram but this are easy to look the movement.

For this I ask if the wobling are normale for this press and if this can make some issue for the cartdridge quality.

I am thinking of changing it, but I am not sure which model yet.
On my press list are: Mec Marksman (#1 on my list)
Redding The Boss Il
RCBS Rockchuker Supreme
RCBS Summit
Forster Co-ax
Redding T-7

Thanks!
