I've got 22 columns in a 1590B a couple of times mounted the conventional way on the back of the pots, but needed a bench grinder to reduce the overhang at both sides. In most cases you wouldn't want to go more than 21 unless you have room to mount it turned 90° and probably upside down with the back of the board at the top. That's the reason why I've tried to make sure the vast majority of the layouts are 21 columns maximum.
Yeah I stayed with your 21 column standard since 22 is so tight! It is possible if you cut the board right up to the holes basically haha. This is how I cut my boards down to width. Normally I would cut it before soldering in the components but this needed to be trimmed to fit in the enclosure
This always gives me a perfectly square and clean cut, without chipping the edge or requiring sanding to get a smooth edge
