The Howa looks neat

I wouldn't. Doing an analysis on hoop stress shows most rifles have a factor of safety well into 5x. A contender barrel is only 20.5mm and has 2 tig welds and 2 scope mount holes right over the chamber areas. Even looking at ar15 or ar10 barrel extensions gives an idea how much "extra" is in most actions. With careful consideration it can be done. Even with huge overpressure loads failures usually occur via barrel splitting vs actions failure. I usually use a kimber as a safe minimum dimensions and they are significantly smaller than a tikka.
