In comparison :
Would you use Buffalo Bore +P ammo in Uberti's Springfield Trapdoor ? They are using modern steel as well but the design is not as strong as most that followed ! I wouldn't use hot Buffalo Bore ammo in my older S&W 629 either....no need ! Maybe contact Uberti and see what they recommend....I already know that my local gunsmith that works on 1873 clones doesn't recommend it !
