One might note that the Contender Pistols are only good to 65,000 psi with small faced rounds like the 357 Max, .223 and 221 Fireball. Larger cases like 30-30 are only safe to 45,000 roughly.
That's what makes that S&W 460V so impressive! 65,000 psi with a .45 cal sized case is really about as big as it gets!
