They actually did both, but as Rifles have had a checkered past in South america as to legislation, the most common firearm by Japanese people living in Brazil was the little 28ga. Murata single shot shotgun. Mine even came equipped with rifle sights but not the paraodx-type rifling that I have seen in some other examples.
The 7x57's were intended for the Mexican Gub-Mint, but over-runs/etc were likley sent to brazil as well.
Psalm 19:14-May these words of my mouth and this meditation of my heart be pleasing in your sight, Lord, my Rock and my Redeemer.
