23.4K psi actually. Handloader #221 had Speer's ballistic lab test this exact load in 2002; 250gr LSWC, CCI-300 primers, & 16.5gr/2400 = 23,413 psi. It was fired in a SAAMI piezo-electric P/V (pressure/velocity) barrel.

As with the M19's, lead accumalation in the forcing cone has been stated as a prime reason for damage to there thin forcing cone/barrel breach.
.
notsofast: If the barrel breach gets split that normally requires a new barrel, as long as it didn't damage the frame. If that barrel is no longer available then it's unfixable.

Compare these two .44 L-frame forcing cones.
