Baldrage's reloading log

[Wobbly]

I loaded up 50 rounds of 115 gr RMR RN with WSF at 5.2 and 5.2 gr. 

So how many did you load at 5.2 and how many at 5.2 ?   

This will be my first attempt at loading HPs, so would like to hear whether there is some consideration I have missed.

Looks about right, but we need an OAL to be sure.
I'm loading PD 124gr HP at 1.100" with 4.7gr WSF.

Wobbly, as stated a few posts back:  "These bullets plunked very short in my SP01 Shadow barrel: ten dummy rounds ranged from 1.0585 up 1.09 OAL, with 1.0645 to 1.0655 being the most common.  Based on those results subtracting .010 - .015, I'm looking at an OAL of ~1.055.  These bullets are .555 long, so seating depth would be .75 + .555 - 1.055 = .250."

D'oh!  I've got to stop posting from my blackberry!

Supposed to read 50 @ 5.2 gr and 50 @ 5.3 gr.

My only point is this... auto pistol load info isn't complete without an OAL. So you're asking for advice, but requiring the reader to go back and dig through 14 pages. That's in the same camp as a "gift" that has requirements tagged on.

Happy Birthday! .... but you have to wash my dog.

Sorry, definitely not my intent to make anyone work to provide advice.  I will re-state my request here, with all the relevant data in one post.

Firearm
? My CZ pistol/rifle model is:  SP01 Shadow Custom
? The caliber of my CZ is:  9 mm
? My CZ has the following changes:  11.5# hammer spring, extended firing pin
? I use this CZ in the following ways:  IDPA
? I want ammo accurate at:  25 yards at power factor 130

Components
? I've been reloading for months/years:  6 months, closing in on 5,000 rounds reloaded
? Fully describe the maker, weight, and type bullet:  Rocky Mountain Reloading 124 gr "Hard Core" Hollow Point plated bullet
? Powder:  WSF; 4.3 - 4.7 gr???
? Primer:  Winchester SPP
? My Cartridge Over-All Length is:  plunk tested at 1.065, so 1.055 nominal COAL

Reloading Equipment
? Press brand and type: Dillon SDB
? Do you have access to a chronograph ?  No

Other Info
? Exactly what is your load data and where did you get it ?  RMR states that their "Hard Core" plated bullets can be loaded to mid-range jacketed, so looking at load data for something comparable (124 gr JHP with WSF, seating depth .250), I see past threads in this forum on Precision Delta 124 gr JHP, 1.09 OAL, load ladder of 4.4 - 4.8 gr WSF (seating depth = .243); Montana Gold 124 gr JHP at 1.065 OAL with 4.7 or 4.8 gr WSF (seating depth .264).  I haven't been able to find any WSF data with 124 gr JHP in any of the manuals that I have access to, but did some find some data for HP-38/Win 231:  Lyman manual has Sierra 125 gr JHP, 1.075 OAL (seating depth = .222), 3.9 - 4.4 gr Win 231; 124 gr HAP, 1.069 OAL, 2.8 - 3.3 gr HP-38 (seating depth = .253).

Problem Area:
Looking for advice interpolating load data to develop a safe load ladder at this very short COAL (1.055). My best estimate is 4.3 - 4.7 gr WSF, at .1 gr increments.   I would greatly appreciate confirmation that this is a conservative load ladder or advice on how to better interpolate data and come up with something better.

Thanks in advance for any words of wisdom!

First of all, forget any type comparison to 231 or any other powder. You can't draw any conclusions or parallels from that.

You can use the velocity/ load table in this thread to develop your own data once you have a chrono. That's about the most help I can give right now.

OK, I'm ready for the next bit of news from Baldrage.

Patience is a virtue.......in reloading.

Holy cats, this should be required reading for all who start down the reloading path!

Baldrage?s log has touched on almost every one of my concerns as a newbie reloader with a Square Deal and the answers were fantastic.  Thanks for the effort put into this thread.
Cheers

Yeah, I thought it was a "novel" approach to a thread when he started, but it really has worked out quite well. And as a resource for new reloaders, it's a jewel. Be sure and also study the "stickies" at the top of the forum if you're new to reloading. Lots of help there too.

Now if we could only get Baldrage back on-line !

Glad to hear someone has found this thread useful!

I'm still around ... haven't updated this thread in a while because I've found a load that works for and have been sticking with it (Precision Delta 124 gr JHP, 3.9 gr HP-38/Win 231).  Thanks to the wealth of knowledge contained in this forum, I've safely reloaded over 6,000 9mm rounds in the last year, and had only one single round that failed to fire (I think it was just a bad primer from the factory, as it was a total dud). 

nstg8r -- if you have any questions as you get started, either about something you've read here, about using the Square Deal, or reloading in general, please don't hesitate to shoot me a PM or post here.

What OAL you are loading PD 124gr JHP?

[nstg8r]

Thanks guys. I?ll have questions I know it, some are rattling around in my head now - just not ready to verbalize them. Usually they wake me up at odd hours during the night. 

I?ve got a bit more refurbishing to do on the Square D yet. I?d better get at it before Christmas takes over.

Not to worry. An attendant is on duty 24/7. Type away !

What OAL you are loading PD 124gr JHP?

Based on plunk test results with my SP01 Shadow, I am using 1.10 OAL for the PD 124 gr JHP.
