Hi all,
I'm hoping someone here who has Quickload could run some numbers for me?
What are the estimated pressures in a cartridge using;
Hornady XTP 158gr
CCI-550
Brass trimmed to 1.25" (so .03" shorter than proper trim length)
HS-6 powder; 7.5gr, 8.0gr and 8.5gr...and maybe 9.0gr?
??
The reason for this question:
----
My mainstay bullet is the Keith 170gr from Rimrock. I can load it mild to wild, but it's a long nose, so won't fit the cylinders in some revolvers. Historically most old timers would simply load it in .38 Spl cases.
I never cared for that too much, just in case my loads ever got mixed into a small J frame 38 or something. I was ecstatic to find out that Hornady once fired brass was 1.25", and Brian Pearce had recommended trimming to this same length for Keith bullets, especially when using old 38-44 load data with the Keith bullets. So that's what I did for a batch of my 357 brass.
Only I've grown tired of keeping this trimmed brass separate from the regular brass. I used to load other jacketed bullets, but I'm down to pretty much only the Keith 170gr, and the Hornady XTP 158gr. Those two bullets do pretty much anything I care about doing. I'm considering trimming all my .357 mag brass to this 1.25" length. That way I could leave my dies set and I'm good to go for either bullet.
I don't shoot hotrod loads. My basic Keith load is 8.0-8.5gr of HS-6 under that bullet in the 1.25" trimmed brass. For example 8.0gr in my 3" SP101 chrono's right around 1050FPS, low SD and ES. Good for target shooting or a woods load in something I might actually have on my person when hiking.
The Hornady XTP 158 gr I also have started to load in a mid-power range (it expands from 700fs - 1400fps). I'm still working up a load which will be accurate in all my revolvers (most 3-4" barrels) and also work well in my .357 Rossi lever rifle.
Right now I'm right around this same charge of 8.0 - 8.5gr of HS-6. I still need to do some testing, but I have run a few of these loads in the shorter 1.25" trimmed brass and I'm liking what I see in the accuracy dept. I seriously doubt 8.5gr of HS-6 is anywhere close to max pressure, but I'm kind of curious what Quickload estimates it at.

P.S. For your own safety I'm not recommending anyone else try these loads. They are my loads and I worked them up in multiple .357 Mag guns over the course of 3-4 years of careful meticulous testing and reading through scads of manuals, new and old. YMMV, IANAL, yada, yada...

One must have a goal, right?
