357 loads?

onereloader · November 4, 2005, 04:06 PM

I just bought a box of hornady 140 gr.XTP for my ruger Security-Six..38/.357 mag. I haven't reloaded anything for this revolver yet as I was given it prior to my Dad's passing..Now, i'd like to reload for it and use it.Only powder I have for pistol reloading is Unique.I have found no data for this bullet and powder combo......any help? I'd like to reload for .38 spl. .38 +P, and for .357 mag....thanks...Rick

Use the data for the 158 grain XTP. It will be a smidge light, but safe.

Unique is a good all around powder, you won't get full magnum performance but they won't be weak either.

Lymans's reloading manual for pistol and revolver (2nd ed) does have Unique data for .357 with a 140 jhp:

4" vented test barrel
1.590 COAL
Start -- 7.0 Vel--949
Max -- 8.9 Vel--1233

From my new .38 Spl "all in 1" book, quoting from the Hornady section they give the following info for Unique, 140 gr XTP JHP in .38 Spl, 4" barrel:

Start: 4.2 gr -- 750 fps
4.7 gr -- 800 fps
5.2 gr -- 850 fps
Max: 5.8 gr -- 900 fps

They don't cite pressures in the Hornady section, and they don't say whether the max is +p.

The Sierra section starts their 140 JHP Unique load (6" barrel) at 5.6 gr -- 850 fps and their max is 6.4 gr -- 1000 fps. Again, they don't specify the pressures or if the max is +p.

The Speer section does not have a "standard" listing for 140 gr JHP's, but they do have a +p section: 6 in barrel, 5.0 gr -- 902 fps and 5.3 gr -- 960 fps. No indication of the pressures other than +p.

It looks to me like the Sierra loads are across the board QUITE hot, not just their 140 gr JHP's, even then you shouldn't have a problem with those in a .357 mag which is designed to handle even hotter stuff.

Appropriate disclaimer -- even though I got this info from real manufacturers' load books (extracted), use at your own risk.
