357/9mm blackhawk

[phonejack]

I recently bought dies and bullets to start reloading 9mm. Out of curiosity I performed the "drop" test with the JHP's into the 9mm cylinder. All fell thru. OK, then I tried some 357/125's and they fell thru also. Now I am wondering about seating a 110 or a 125 .357 bullet to the same seating depth as a comparable 9mm bullet and trying that in the blackhawk. Dumb idea ? Any thoughts ?

My 9mm cylinder likes .358 cast boolits and power pistol.

ALL MOST ALL FOREIGN 9MM PARABELLUM BARRELS are .357" I.D. The only American 9MM barrels that adhere to the so-called 9MM size, .355" I.D., are the ones made by S&W for their 9MM pistols starting with the M39 in the mid '50's. YOU can bet your ranch BR,SR used only 38/357MAG size BBLS in His SA convertibles.

Save yourself a lot of trouble and just measure the bullets. A half decent micrometer will solve the question of what size bullet to shoot through your cylinder...

You might get away with .357-.358 bullets in your convertible if they headspace ok but I doubt they will work in a 9mm semi-auto with a .355 barrel.

LET ME NOTE THIS : I have used .358" bullets in 9MMPARABELLUM pistols for 50 years with no untoward problems. Even the old style Speer 158GR SWC swedged bullets went through my old S&W M39-2 slick as pppphhhiitt through a goose and were highly accurate.

I haven't been doing it that long but for many years my 9MMs have been shooting .357 jacketed bullet handloads very well. Haven't tried the .358 cast yet.

There is an excellent thread on the cast boolits site on loading cast in 9mm. It will save you a lot of problems.

We go to a lot of trouble to load ammo safely by the book. When I look at what the manufacturers say for 9mm it is .355 jacketed and .356 lead.

A Blackhawk convertible definitely has a .357 barrel and would be safe with .357 jacketed and .358 lead bullets.

I would really like to see what the pressure of shooting a .357 jacketed bullet through a .355 barrel is?

JIMBO, it makes no difference to speak of whatsoever.
