A buddy of mine got a nice made in 1969, model 15 with box & documents. One document was on ammo. If these velocities are legit it looks like they all can handle hotter ammo than is offered today. This would have been before there was an an official SAMMI specification for Plus P.
The numbers are legit, but there are two things to be aware of (this has been discussed here before). 1) The especially fast 38 Specials were intended for revolvers intended for "hi-speed" ammo, like the large framed S&W 38-44 (N frame) and Colt Shooting Master. 2) The velocities for 38 special are from 6" barrels, where today they are from 4" barrels. The 357 magnum velocities were from 8 3/8" barrels, where today they are from 4" barrels.
