If we're sticking to SAAMI blessed cartridges, I'd be in for a 6 Creedmoor, No 2 weight @ anywhere from 21-24".
Stock color isn't important, but something that imitated a McSwirly would be neat.

If we're venturing outside of SAAMI, 22 Creed has my interest.

There is nothing made by man,
which cannot be broken by woman.
