However, using your reloads in a SD situation is a bad idea, so I've been told.  In an emergency different story...

...
Yeah, reloads for self defense is a bad idea.
It's a legal thing.
Btw, I used to order plenty from wideners in my past life. I loved their country style.

oldfart is saying that his equivalent "head" to GDHP is the extreme, and these are cheaper than MG
he is testing 124 gr extreme and trying to come up with a practice equivalent to the factory speer GDHP

Got it.

GDHP have been in use, I believe, with LAPD for a long time.  In an ITTS class uncle scotty informed us that they went to GDHP's due to it being a bonded jacket for barrier and windshield penetration.  Also, he preferred 45 then 9mm.  I assume HPD went to a GDHP due to it being bonded as well.

You could post this under deals and sales.
Somebody might be interested in doing some 38 spec +p loads or light 357 mag loads.
It looks like they are trying to push 1 item per day. 7pm to 7pm is the adjusted time of the sales.

Since CFE Pistol is the only handgun powder I could find locally, I bought some and tested it for the purpose of this project.
As it turns out, it works quite nicely:
4.8 too slow
5.1 too slow
5.5 too high
On my next trip, I'll run 5.4 which should be perfect.
It's worth noting that at 5.5gr., I fired a 5-shot test group at 25 yds that had 4 shots in a 1.25 in. cluster but spoiled by 1 flier.
So that indicates a fine potential for accuracy.
Point of impact was approximately the same.
In conclusion, cfe and xtreme 124hp works well in simulating the gdhp for every day practice.
At current prices, it comes out to $8.25/per box of 50.... Not too bad eh?

Final update
Went to the range today.
I loaded a batch of 124 xtreme php with 5.4 cfe, fed gm100, fc cases
Recall that the desired velocity is1070 fps from my test gun 3913.
The load checked in at 1065 with sd of 9.
Accuracy at 25 yards was excellent, except for that 1 flyer.
Estimated cost at current market is $8.50 per 50 rounds.
Actual gold dot 124 ammo runs about $1 per round, so this is great practice ammo.
See the pic.

Great info,  I've wanted to try the xtreme 124 gr HPs.   I found my extreme 124 gr hpcb to run good at 5.1-5.2 gr CFE-P at 1.18 coal with cci small pistol primers.  I don't have a chronograph , but maybe I should try work up the load a bit.

If you are just loading practice ammo then you don't need a chrono. Just diddle with the powder charge until you can bench a fairly tight group.
If you loading for combat competition, then you might need to use a chrono to make sure your  loads make minimum power factor. But if you go too low then the ammo might fail to drop a steel popper target.
If you loading for bullseye competition, then you are shooting the wrong gun.

Haha it will be awhile before I jump onto the 1911 bandwagon.  Maybe when I can start affording 45s

I'm just messin' with ya.

But seriously,
In retrospect, if I was starting out all over again I would not buy a 1911.
I would choose a glock 45 auto with aftermarket bbl.
Or a spring.xd. 45 auto.

I'll keep that in mind for the future. 

Update 6.17.15
Here are some speed numbers using my new glock 17.
Speer 124 jhp gold dots. Av. 1113 fps sd=18
Xtreme 124 php simulator 5.4 cfe pistol. Av. 1124 sd=7

So my recipe for the gold dot simulator still stands as a viable realistic practice round for defensive shooting.
The only disturbing thing I noticed is that this block17 does not seem as accurate as fanboys say it is.
But that is different topic altogether. See the pic.

I'll go to the range with you and let me try my G17 to shoot some of your rounds in.....I'm real accurate. And if not I can use your ammo

Tell me what is real accurate in your gun. Factory ammo? Reloads?
What is your typical group size at 25 yds from a benchrest?
Running a stock bbl?
Keep in mind this ammo was not tuned for accuracy, it is tuned to simulate the look and feel of hpd service ammo.
I have been wondering about stock glock accuracy for a long time.

O.F. I'm going to start loading some GDHP for practice similar to what I believe you're doing and use factory GDHP 124 gr. for the real thing.   But my main goal is to test HPs with Glock single stack mags for function with similar recoiling rounds and for best accuracy.
I only have AA # 7 and Autocomp for pistol since that's what was available and plan on using Lee 4 die set with Pro Autodisk  on a 550B.   
Powder load data for AA # 7 only has a 1 grain window and less than 1 gr. for Autocomp.   What kind of powder measure are you using?    I'm thinking need to either trickle charge and weigh each charge especially for the AA #7 which is very fine and likes to find leak paths.  How are you dropping powder and what increments do you use?   Still learning so questions may seem lolo.

Mic808 told me about his struggles with the lee powder measures. I have one that I was going to try out, but have not got around to it yet.
Anyway, I use dillon loading presses with the dillon measures.
I know aa7 is pretty fine grain. How about that autocomp powder? Bigger granules? I never tried it.
Re. Increments...from previous experience with manufacturer supplied load data, I tend to start on the high side because their data is usually pretty conservative.
To get a good copycat load, you have to clock the factory ammo from your gun to establish a reference. Then I would do 2 load tests.
One just over minimum and one just under max.
When you clock those 2 loads it will be pretty easy to dial in your copycat load.

Some tips...
Sort your brass
Lube the shell before sizing
Drop 5 to 10 charges into the pan and take the average
Go easy on the lee factory crimp die. I prefer a taper crimp myself.
If you don't have  chrono, I can run tests.

i have that problem when i first reload my ammo using ramshot trueblue bc of the tiny small ball powder. but after i tried hodgdon clays and bullseye. it meters well on my Lee powder measure using Load Master.

O.F. mahalo for the increment info and tips.   Autocomp is bigger than AA #7 but never tried to meter in Pro disk.   Will try both and if leaks I will use the Dillon powder measure and die.   Was just lazy in cleaning out different powders and cheap Charlie in buying a 2nd Dillon since I got the Lee.
You lube every case even using carbide dies?   I wasn't sure of the amount of crimp but will lighten up just to remove the bell.   I don't have a chrono for pistol use and appreciate your help in testing my loads. 

Mic808 you had powder leaks with the Lee?   Do you have the Pro or Auto disk measure and do you use the charge bar or disks?   I also have 1 lb. of True blue unopened so mahalo for the tip.   I would get Bullseye  or similar powder if available but seems to be out.  Since I got the AA #7, will use it up and look out for larger ball powder.

I will let you guys know how the Autocomp works in the Lee Pro.   BTW just saw that Bing has good pics of some different powders when you search for Hodgdon, Accurate etc. powders. 
Thanks for your help and replies.

i have the pro auto on my load master. with the disk. try and ask around to trade your trueblue for some similar powder flake like BE.
