[zymguy]

guess ill be buying some starline 38 spec +p headstamp brass.
Is anyone crimping this bullet over the driving band in 357 mag brass?

I have to crimp over the driving band for a few of my revolvers. Its not a problem, just start low and work up your load to reflect the reduced case capacity.

[tazman]

Many 357 magnum revolvers have cylinders that are too short for the 358429 boolit. Lots of reloaders choose to crimp over the front driving band to get clearance.
As was mentioned before, just start lower and work up. You will be fine.
It would also give you an excuse to buy another revolver.

[Tatume]

Both ways work; crimp over the driving band or use 38 Special cases. As you noted, the +p cases are preferred, but Starline makes good cases, always.

[Nueces]

Reading the notes on Starline's 38 cases, they claim for their +P cases: "38 SPL+P has no difference from the standard 38 SPL, other than headstamp designation for load segregation. This is due to the fact that our standard case design will handle +P pressures with no problems."

I like to trim 357 cases just sufficiently to allow normal seating and crimping with the long 358429. I get a bit more powder room and those rounds are unlikely to chamber in a standard 38.

The 358429 has varied a little from production run to production run. I had 2 SC and they were minorly different. One of them worked with normal crimp in Ruger NMBH and the other was too long. My Dan Wesson (old) works fine with the Ruger load. I sold off 2 S&W Model 28's simply because of the short cylinders. I sold the long SC mold too.

I'm shooting these 358429s in a Rossi '92 crimped midway on the front band. That can work too.

thats an option in my budget !

I have shot 358429 lightly taper crimped on the front drive band forever. I've never had a problem with bullet movement in max mag loads. Lyman cast bullet handbook load data for 358429 shows the oal as crimped on the front of the drive band.

I crimp in the crimp groove for my NMBH and they fit. They are pretty much flush with the front of the cylinder though.

I accumulated some notes after measuring loaded rounds and cylinder lengths for a good variety of wheelers. Note that all cylinder length measurements include the case rims, typically 0.055". I expect the formatting to vanish when posted.

Overall lengths: 32-20 with 31133 is 1.58 OAL, 327 with 31133 is 1.49, 357 with 173 gr Keith is 1.66, 38 is 1.53, also with 358156 seated out. 44 Special, with 429421HP is 1.57. 357 case trimmed to 1.24” max will chamber in M-27 with Keith bullet. Colt OM cylinder too short for 32-20 or 22 Kay-Chuk, would work with 327.

Cylinder lengths, include 0.055” centerfire rim.

From inspection, you can see that only the Smith M19 or 66 and the Colt New Service or Shooting Master are comfortably able to swallow a long seated 358429 in a full length 357 case.

I, too crimp to make cartridges work in some revolvers/rifles

haven't had a problem with them collapsing in magazine tubes so figure my crimp is tight enough

[Cowboy_Dan]

I just checked my dummy in the die box, and for my dad's Security-6 I seat it until the crimp groove just disappears and crimp into the driving band. Your mileage will likely vary.

i have been using the 358429 in 357 cases crimped on the front driving band for years.it works great. the 358429 was designed for the 38 spl.case for use in the .38-44 s&w.

i use the 358429 for heavy loads in.38 spl. cases. mainly because .38 spl. brass is so cheap. i have 3 buckets full of it now. it works slick through my rossi 92 carbine also.

Works in my two Ruger Blackhawks but too long to feed in the Marlin M1894. I went to the RCBS 38-162-SWC and it works well in all of them./beagle
