When 158 grain bullets have no problem going 1000-1250fps?
I'd think a 125/130 should easily be able to do the same.

1250 is .357 mag. velocity. I clocked 900fps with 125 in a 2" 642, that's fast.Quote:

Funny thing, and something I thought about starting a thread relating to this. Very similar modern revolvers are chambered in .38 SPL, 357 magnum and 9x19mm. The latter two generate the same pressure. .38 Spl is spec'ed for much less. We all know why this is (.38 Spl is such an old cartridge, there are still early guns around that can't take nearly the chamber pressures modern guns can.) But, of course by now modern guns predominate. I'm a little surprised that some "rogue" ammo maker doesn't put out a .38 super +p+ that at least approaches 9mm/.357 Magnum pressures, and explicitly declare that the ammo should only be used in guns manufactured after 1970 (to randomly pick a date.) It would have a disclaimer about the overpressure, so if it kabooms your gun, it's on you.

I have not chronographed my reloads but 5.2 with unique and 158gr hard cast gives me great accuracy and is much cleaner to shoot than loads under 5grains in terms of leading and carbon or unburnt powder.
And color me surprised. Exactly what I was looking for.

I'm kind of surprised manufacturers don't do that with the 9mm since it's only 4 years younger than the .38 special.Quote:

I would LOVE to see independent pressure testing of those 38 spl +P loadings that get close to 357 mag velocities...
I'm guessing we would run screaming into the night if we saw what some of those loads were doing pressure wise.Quote:
