Max Loading for .357 Mag with 2400

[Mike SC Hunter]

I would imagine most of the respondents here use a chronograph. I've used six in the last forty+ years. Recorded velocities have been pretty similar from a cheap Chrony to an Oehler 35P.

I've my Oehler 35P for over 30 years.........It works.

I used mine for thirty or more years as well. The printer went back once for a rebuild (maybe replacement ) after many years. However, I stopped using the Oehler after I bought a LabRadar some years back. Certainly not a better chronograph than the 35P, just easier to set up.

I go with what's most accurate. For me, it's 12 /2400 with the 160 grain H&G #51 plainbase, the original .357 bullet, 13 /2400 with the 162 grain Lyman gas checked design #358156, 13 /2400 with the Lyman #358429 SWC, 12 /2400 with the Lyman #358349 155 grain HP, and 12 /2400 with the LBT WFN 180 grain plain base, 12.5 /2400 with the NOE 360-158 158 grain WFN plain base.

The most accurate has been the H&G #51, with the #358156 not far behind, but the others do pretty well.

What make of Powder are you using in these loads???

For me I find 11.5 grains of 2400 will put all my shots in the 10 & 10X ring at 15 yards. I tried some 14.4 grains of 2400 this morning. Stout and will stay in the bull at 15 yards. Both loads were 158 grain SWC's. The older I get the less I shoot the barn burner loads. Appreciate the info.

When I was shooting the 14.4 grains of 2400 with the 158 grain SWC's, it got everyone on the range's attention. Really load out of the M27 3.5 inch!
