New Loading Data From Alliant

[Col. Mortimer]

I was concerned regarding the load for Power Pistol as different book had significantly data. I emailed Alliant and received the following data that is different for Power Pistol. The Alliant web site and some books had a maximum load of 6.4 gr. for 124/125 gr. bullets. I did not check the other powders and bullet weights. The email said they used Speer bullets for the web site, inplying the differences are due to the bullet type. I hope this info keeps everyone safe.

9mm Luger

115 gr lead bullet
Bullseye start 4 grs max 4.5 grs
Unique start 4.5 max 5 grs
Power Pistol start 5 grs max 5.5 grs

115 gr jacketed bullet
Bullseye start 4 grs max 4.5 grs
Unique start 4.5 grs max 5.5 grs
Power Pistol start 5.9 grs max 6.3 grs

124/125 gr lead
Bullseye start 3.8 grs max 4.3 grs
Unique start 4 grs max 4.5 grs
Power Pistol start 4.8 grs max 5.3 grs

124/125 gr jacketed
Bullseye start 3.9 grs max 4.3 grs
Unique start 4.5 grs max 5 grs
Power Pistol start 5 grs max 5.5 grs

147 gr lead
Bullseye start 2.8 grs max 3.3 grs
Unique start 3.2 grs max 3.6 grs
Power Pistol start 4 grs max 4.5 grs

147 gr jacketed
Unique start 4 grs max 4.5 grs
Power Pistol start 4.5 grs max 5 grs

Note: Start with the minimum charge wt. Reload just a few and be sure they will properly cycle the action of your pistol before reloading a quantity.

Good to know. Thanks for sharing.

Well, that is very interesting information.

They are correct. Different bullet construction surely makes a difference. The Gold Dot is a very unique bullet.

You have to wonder why they don't have that data available via the web site.

Just a guess...
They want you to buy Gold Dot bullets.

I wish they would list more lead bullet loads using Power Pistol. I've found it (based on WESHOOT2's recommendations) to be fantastic in revolver cartridges with cast lead, and recently I've been experimenting with it in .45 Auto in my 1911 using 230 gr. LRN. I worked up to 7 grains and found terrific accuracy, but I'm concerned I might be in +P territory (have not chrono'd this load yet). I sent Alliant an email asking for their input.

I know it sounds ridiculous, but I think Alliant doesn't know what they are
talking about.

I load a 120 gr lead bullet over 5.0 grains of Unique, and it is a LIGHT load.
My 2004 Alliant guide says 5.5 grains of Unique is max for 125 gr lead
bullet. Makes alot more sense than 4.5 max.

As for the jacketed bullet, this is what Alliant's website says:

5.8 grains of Unique as max. Their words.

Call me "stupid", but some of the comments here and the load data from Alliant have me confused.

According to their web site they list the Gold Dot HP in the 9mm. They list the following.

115gr GDHP
Unique-6.3gr
Bullseye-4.7gr

124gr GDHP
Unique-5.8gr
Bullseye-4.4gr

147gr GDHP
Unique-4.3gr

Their online GD data is not even close to the data you received by email. Either I am totally confused or the guy that sent you the email was even more confused.

Just kidding. It is obvious there is a huge difference. It may be the data can vary depending on the bullet type. Check the Accurate Arms reloading data for examples. There seems to be a wide spread in load data for Power Pistol. You will notice the online data specifically references GD bullets. I posted this info as a reminder that different bullets can result in significantly difference results. That's why it is always smart to start with the minimum load and chrono to check your results with different bullets. If you have worked up a safe load, you're fine and don't sweat it.

According to Speer/Alliant the Gold Dot loads the same as their plain old TMJ and JHP. That would be 115gr = 6.2-6.7gr Power Pistol for all three bullets only one being a Gold Dot. No difference at all really.

[Nick A]

It's hard for some folks to believe, but the Speer Gold Dot is a copper plated bullet.

It is not jacketed.



http://www.speer-ammo.com/products/gold_dot_const.aspx

Uni-Cor technology bonds an incredibly uniform jacket to the core - one molecule at a time.

That's what they mean by "one molecule at a time". The lead core is electroplated with a copper coating just like Berrys, Rainier, Xtreme, Powerbond & Frontier.

Same with their TMJ bullet. It's a plated bullet also.

So what "Bullet Type" is this new data using??

I mentioned in my email I was using Zero bullets. I was concerned when I checked the primers (CCI) and they seemed to be slightly bulged. It was not cratering. More like a gently sloping mound rather than a steep ring around the firing pin indent. The Sierra manual shows a max load of 5.7 gr. so their data is in line with this data. I noticed in the Accurate Arms chart, the load varies significantly depending on the brand of bullet.

Well that is surprising. Just today I loaded small batches of 124g. Golden Sabers in 9mm. in 4 different loads. The load data was gathered from the Speer book and the Alliant website.

5.7, 5.9, 6.1 and 6.3 grains of Power Pistol with an OAL of 1.125. Using a Glock 17 with factory barrel and a Springfield EMP I worked my way up with both and had great results. All the primers and brass looked great and they were very accurate as well. Stout recoil in the higher charges and HUGE fireballs in the EMP but that is what I expected. I did not have a chronograph available today but I saved 10 rounds of each to chrono in both guns later.

So is this unsafe?

What type of primers did you use? I used CCI SSP and with 5.5 gr. I had a bulged area around the general area of the firing pin indent. Not a crater, more of a Mosquito bite.

The velocities may be more useful. Please let us know your stats. According to the Sierra and Lyman books, you are above max load of 5.7 gr. If you see pressure signs, you may have already pasted safe limits.

Power Pistol is a slow powder and may not be suitable for short barrel pistols. I have no flash with a 92FS with a 5" barrel.
