The main reason I posted this one, is that the Fort Scott Ammo company had this shown as the load on their web page.  In my opinion if they are loading 13 grains of Alliant Power Pistol it would be a problem and possible dangerous load.
10 Round, I appreciate that offer but ...
10 Round, any handloader could do a careful pull-down an take a good picture of the powder and weigh what's inside to verify. If I could see the picture of the powder, it is possible I could ID it.

Mailing ammo is not a cost-effective deal. Also, because USPS is not allowed.

As a side note:
The most Power Pistol powder I saw loaded was Buffalo Bore with the Barnes 155 TAC-XP where they loaded 11.0 grains and the powder was very compressed with that Solid Copper...

Thanks for the update info and your taking care of things here.

Send me your address, I'll order it and have it shipped to you as I live in California. I don't order ammo. You can send me what's left

And now it has been moved to Wednesday night.  And it is completed.

We are up to date on the latest version of the forum software.

Smith & Wesson® Red, White, and Big Blue Mountain Gun Giveaway!

This has been moved to Thursday night.

There is an upgrade to the forum software available.  I will be performing this upgrade on the UAT version of the site tonight. This will not impact this production website.  If that upgrade is successful (and I expect it will be), then I will upgrade this production site tomorrow night, around 9:00 PM MDT.  It should be a minimal downtime upgrade, so chances are it will be un-noticed.  But if you have a hiccup or error tomorrow night around that time, that is why.

10MM SCS® TUI® - 190Gr Solid Copper Ammo 

https://fortscottmunitions.com/collections/handgun-ammo/products/10mm-scs-tui-190gr-solid-copper-ammo-copy

I would do a pull down documentation to see what's actually being used as powder.
They show 13 grains of Power Pistol as the load for this ammo. It would seem to be way much for a 190- grain bullet especially a LONG SOLID COPPER which will be longer than a lead or lead core bullet!
If I had some I'd do that documentation...

I found CBC / Magtech primer pockets to be on the tight side with some makes of primers.

My CBC headstamp brass came from Magtech ammo.  I have not had any issues with it.

I just grabbed a handful of brass from the bin.  These have been wet tumbled and sized/decapped.  My handful included 3 CBC, 4 FC, 4 Win, 3 Starline and 3 RP.  I measured them all and the CBC were not in any way outliers.  Primer pockets measured .206" except one RP that came in at .207".  Depth was between .120" (FC) and .125" (RP) with most being .122-.123".  The CBC all measured .122" depth.

About the only thing of note on inspection is the CBC brass did have the three-point stake on the primer pocket.  I don't ever remember having an issue seating primers in this brass.  I have been shooting some newer magtech lately and it is possible I just haven't reloaded any with the staked pockets yet.
