Taurus makes three designs in 45LC. If it's the Raging Bull, it was designed to handle pressures beyond 100K CUP and can handle anything you can throw at it. The model 450 is quite a bit less hardy, but will handle any factory ammunition offering well. The 450T on the other hand is strictly standard jacketed ammunitions only. The stainless steel barrel is swaged into the titanium shroud and can be damaged by lead bullets and high pressure ammo. The guns have had there share of problems, but they are a sound gun, backed by a lifetime warranty. Good value for the money.
