The following is the response that I received from the Speer Technical supervisor:

James, we did a rebrand in January and it is 54000GD, same ammunition.

I hope that I am wrong but I bet that SGAmmo will no longer receive the cheaper priced SKU 54000.  Dang it!

I checked the Speer website and it only shows the 54000GD, which is the current one in stock at SGAmmo,https://www.speer-ammo.com/products/ammunition/gold-dot?page=0&facets=computed_skucaliber_s=10mm%20Auto . 

I have not contacted Speer so I have no idea if they are currently keeping the 54000 SKU in the line.  I hope that they are as I would much rather pay the cheaper price.

Edit-  I just contacted Speer via their website and asked if the 54000 was still in production, being produced on a limited basis, or if it has been replaced by 54000GD.

Even at $23.00 it's way better than most

Yes it is a pretty good price.  Another thing or two that I would like to mention is that it feeds great in my pistols.  At the velocity that it is loaded it meets my needs.  I will never be in bear country so this loading from Speer meets my needs perfectly.  Whole I love to shoot the hot 10mm stuff(and do so often), to me this loading is perfect for self defense loads. 

About a year ago I bought a case of that from SGAmmo for that price per box.  Even though they still show that on their site as out of stock, they also have the same ammo but with a new SKU and new Speer box at $23.95 per box https://www.sgammo.com/product/10mm-auto-ammo/20-round-box-10mm-auto-200-grain-gdhp-speer-gold-dot-hollow-point-ammo-54000g .  I've often wondered if the $11.95 per box was a pricing error by SGAmmo because I have not been able to find that ammo that cheap anywhere else.  If it comes back in stock at $11.95 per box I will certainly buy another case at that price.   

Geeman - Thanks for posting this, I just ordered the 8# jug of BE-86.  This was the last powder on my "got to have " list.   

Last Friday I ran a box of these through a 5" Wilson Combat 1911 and a 6" Nighthawk Long Slide.  Velocities were a little lower for me but still decent 10mm loads.

5" Wilson       1204 FPS average for 9 shots
6" Nighthawk 1237.6 FPS average for 9 shots

As a side note, in comparing the Sig cases to Starline cases, I noticed that the flash hole on the Sig cases is smaller than the Starline flash hole.

 

Intercooler - Thanks for the report, after reading it I ordered 10 boxes.  I haven't been able to get to the range for a while but I will be ready to try these in the EAA Match and Limited Pro.  If time allows I will run a few of them through the Heinie Logh Slide and the Wilson Tactical Elite too.  And if the range conditions permit I will shoot these over the chronograph.  It might be a couple of weeks before I can get to the range but will give a report once I go. 

I came this close, I mean this close, to getting the black panels.  But for some reason just had to try something different from what I usually would have done.  Now if I would have got zombie green the grandsons would think that I was the coolest

Friday I received 4 more of the Nighthawk factory mags, giving me a total of 6 Nighthawk mags.  I think that these are Metalform mag bodies with CMC internals.  So early this morning I took these mags and the Long Slide and ran 133 rounds through it with no malfunctions.  I had previously tested some Wilson and Tripp mags and had too many malfunctions.

I also took along a Wilson Tactical Elite and tried the Nighthawk mags in it.  Fired 93 rounds and had 2 malfunctions on the last mag.  I was using reloads with a mixture of cases (Starline, PMC, Federal and Armscor).  Each case has been reloaded a number of times so that may have been a factor with the malfunctions.  Additionally, I keep saying that I'm going to limit myself to 100-150 10mm rounds per session, but I'm having toooo much fun.

Here's a picture from this mornings outing:

You started this 


Now don't forget to add two of these to your collection 

I already have a severe 1911 addition, and yes, I think that the Witness bug has bitten me too.

Looks good man! That's a different color.

Thanks Intercooler for recommending these panels and Jim at J&L.  Swapping the factory panels for the Extreme ones shaved about 2 tenths of an inch.  This really helped me get a better grip on the pistol.

I'm still not sure why I went with the colored panels, but I'm glad that I did.  Even thought about having the hammer, slide stop, and safety cerakoted too.  

Yesterday I received the Extreme grip panels from Jim at J&L Gunsmithing.  Got them on today and had to take a picture -

Monday I took the Long Slide for it's second trip to the range, firing a total of 90 rounds through it.  Factory rounds were Remington 180 grain FMJ, Georgia Arms 180 grain FMJ, and the "Delta" 180 grain offering from Underwood.  Reloads were topped with Zero 200 grain FMJ and Montana Gold 180 grain JHP.  Results were the same as from the first range trip.  Accuracy was good but the pistol would only function with the 2 mas that came with it.  My old reliable Tripp mags did not work at all, and only one of two Wilson mags worked.  Once again, the magazine issues were the same on both trips.

The above mag issue does not surprise me as I learned that a 10mm 1911 can be real picky about their mags.  That's fine but I certainly need more than 2 mags that will run in the long Slide.  Yesterday I called Nighthawk and discussed my mag situation with them.  I was told that the two mags that came with the pistol were tuned for it.  I ordered 4 more of their mags and will see how they do.  I like this pistol a lot, so I don't mind a little juggling with the mags.  If needed, I will either get several more of their mags and have them tune them, or send it off to Virgil Tripp and have him tune several of his mags.  I hope that I will not have to do this but will if it proves to be necessary.

Monday I got a chance to dash out to the range and try out the new Match.  As I was doing some other shooting I only had time to run 56 rounds through it.  The only factory ammo shot was Georgia Arms 18o grain FMJ.  My reloads consisted of the Zero 200 grain FMJ and Montana Gold 180 grain JHP.  Rounds were fired through 5 different K-10 magazines.  No malfunctions or other unpleasant surprises were encountered.  As this pistol is still box stock none of the rounds fired exceeded 1200 fps.

I have fired the above ammo in my Elite Pro and so far the Pro shot each load a little better than the Match.  But I know that my eyes and aging hands may have affected Monday's shooting too. 

Once again I was surprised how well the Witness line handles the recoil of the 10mm.  Just seems a little softer to the hands than when fired in the 1911 format. 

I need to order some of Henning's parts for the Match, will do so soon. 

I still have some thoughts that I need to add comparing the Match to the Pro, will do so soon.

Some venders/makers use "TMJ" for plated, and after looking at the picture you can see where the base is plated.  Just for comparison, E-XTREME-Bullets has their 200 plated for just a little cheaper - http://www.xtremebullets.com/10-40-200-RNFP-p/xc1040-200rnfp-b0500.htm
E-TREME has free shipping through the end of September vs Palmetto's in a ammo can but with postage added.

I like the Zero FMJ 200 grain bullet, just ordered some more from Powder Valley last night.  $229.00 for 2,000 plus shipping brings the total to about $247.00, or $61.75 per 500.

As a side note I have shot a lot of plated bullets from Berry's, Ranier, X-Treme and PowerBond.  They shoot fine for me, really like 'em in the .380, 9mm, 45ACP, and 10mm.
