.357mag 180gr subsonic

Scott10d · July 4, 2013, 03:12 PM

Has any one loaded .357 with 180gr xtp subsonic?
Trying to find info on a load.thanks for any info.
It in a rifle with 16" barrel single shot bolt.

Look up data for the .357 Magnum pistol at the Hodgdon data site. It's for the 10" barrel used in their pistol data, they have a starting load of Longshot for the 180 grain Nosler Partition that should be just under the speed of sound from a 16" barrel. You could also email Hornady for data specific to their bullet.

Scott10d · July 4, 2013, 05:17 PM

Dang thanks I looked there earlier and only thing I seen was 170gr.dont know what I did.

Misssissippi Dave · July 4, 2013, 09:24 PM

You can always load .357 magnum down to even .38 special loads if you wanted to. There are several people that do this so they can use the same case for both in revolvers.

WESHOOT2 · July 5, 2013, 06:16 AM

For subsonic with that bullet recommend Alliant Power Pistol or Hodgdon HS6.

Salmoneye · July 5, 2013, 06:19 AM

Alliant 2004 manual:

180gr FP Bullet

5.3gr Red Dot for 930fps

4.9gr American Select for 850fps

Thanks for info I think I know where I can get select at.

One of the most, if not the most pressure stable powders you could use for this would be Ramshot True Blue. Especially considering that many powders will only give 50% or less load density for the type of load you desire with the exception that AA XMP-5744 could be used for higher load density, providing you can find data. AA#7 would be next on my list. There is new data at www.ramshot.com that covers both True Blue and AA#7 since they're both owned by Western Powder Co. Unfortunately, at 180 grs., they only loaded with a cast bullet, but if you email them and explain what you're attempting to do, I'm sure Rob Behr will be glad to give you data for either True Blue or AA#7 for the 180 gr. XTP loaded sub-sonic and you might want to inquire about the use of 5744 that's at its best for lower velocity with high load density in magnum revolver cartridges.

Scott10d · July 10, 2013, 08:24 PM

Thanks for all the info now I just have to find some powder.

Well sorta, I do this with powders that are acceptable for 38 spl, and the slower powders maybe more appropriate for you. I would think VV N340 or Universal would be good choices, but I am just guessing.

WESHOOT2 · July 11, 2013, 05:27 AM

Universal is my go-to for anything non-nuke 357 Magnum, and many easy-shooting 38 Special.
I use it under lead, plated, and jacketed.

Scott10d · July 12, 2013, 04:07 PM

Thanks for all the info I emailed ramshot got info in a hour from rob .still have not got anything back from hodgdon.

57K · July 12, 2013, 11:43 PM

I doubt that there's anyone in the business more eager to help then Western's ballistician, Rob Behr. There is plenty of data for jacketed, cast and plated bullets at both Ramshot and Accurate's website. For anything other than full-power loads, True Blue will be hard to beat. It's a very dense spherical and very small in grain size so it will meter exceptionally. I much prefer spherical (ball-type) powders to flake powders in high pressure cartridges. I use True Blue for my 125 gr. - 158 gr. .357 Magnum handloads that I shoot and carry in my Ruger Speed-Six that has a 2 3/4 barrel. Hopefully, Rob was able to help you with the 180 gr. XTP.

Scott10d · July 23, 2013, 03:40 PM

I went with 5gr titegroup for average 1036 fps with only 5fps spread.

AlaskaMike · July 24, 2013, 02:35 PM

The problem with driving a jacketed bullet slowly in a rifle or carbine length barrel is the increased risk of lodging the bullet in the barrel. Your use of a relatively heavy for caliber bullet will help mitigate the risk somewhat (the heavier bullet having more inertia).

If you're already aware of this, then that's great but I thought it was worth pointing out.

Mike

Scott10d · July 24, 2013, 06:06 PM

I shot around 20 rounds with no problem so fare.

AlaskaMike · July 25, 2013, 01:42 PM

Scott--I think where people start to get into trouble is when they go significantly slower than 1000 fps out of the rifle or carbine barrel.

Mike

57K · July 25, 2013, 04:45 PM

With a 180 gr. XTP at 1036 FPS, you have nothing to worry about so long as that is a safe charge of TiteGroup. I am not a fan of TiteGroup and particularly not in high pressure cartridges, but an extreme spread of only 5 FPS is outstanding. If this load meets your accuracy expectations, I think I would stick with it until you have a need to push the 180 faster. I would not try to load faster or to the Max. Charge of TiteGroup.

Scott10d · July 25, 2013, 09:37 PM

I like to stay on the low side with titegroup because of pressure.groups are great 4shot groups at 45yards is less than 3/4" out of 15 shoots the range was from 1034 to 1039fps very pleased.

ChaperallCat · July 26, 2013, 01:28 AM

Well its a worthy idea but, getting any expansion? lot cheaper to use lead if your not bothering with expansion.
