What kind of wire are using? The only time I have had a stranded wire snap is
when I accidentally nicked the wires with the wire strippers.

What I usually do when I attach wires to a vector board or a PCB is
use Vector K24A
pins. I solder the pins to the board and then solder the wires to the
pins. If the
holes are too large for K24A pins check out Mill-max for some larger pins.

If the holes are only slightly off (from the .156" pattern) and the board is
one or two layers you may be able to drill it.
