Yep, looks like large... thanks.

Going to order some, I reload, and want all my brass to be the same.

AAC or Ammo, Inc? Those are two different companies I think

AAC, America's Ammo Company.

Thats what I thought. Not sure what benefits the photo of Ammo Inc above has then.

Off Palmetto’s page for the AAC 10mm 180 gr FMJ

Well crap, that's the first place I looked but apparently I missed it... thanks.

Just pointing out the specific ammo I got...

Not sure how common it is but it is out there.

Is this ammo .40 or real 10mm? I’m just curious if anyone has chronographed it…

According to this vid, the chrono-ed 5-shot average = 1222fps from a Sig X-Ten.



With the ubiquitous 180grn 10mm FMJ bullet in factory range/practice ammo, you can do better with MagTech, Sig, or certainly UW’s “Range Supply” ammo. All of those are pushing the 180grn slugs into the 1240fps-1270fps range.

Supposedly, the CCI/Blazer ‘brass’ 180grn 10mm ammo is doing 1200fps, but we haven’t chrono-ed it.

Put some Blazer 180 FMJ by the ol' LabRadar a while back.

Ruger SR1911 5", 16 shot string:

• Avg velocity - 1169fps
• ES - 44fps
• SD - 13fps

M&P 10 4.6", 14 shot string:

• Avg velocity - 1126fps
• ES - 35fps
• SD - 10fps

Thanks Nick....

Our Federal 180gr is barely making supersonic in a 4.6" barrel

You can do better than the Federal Champion 180grn ammo for general range/practice 10mm fodder, as mentioned above: UW, Sig, or MagTech. Choose your price-point.

Personally, where I’ve noticed a slight uptick in real (legit) 10mm offerings from the mainstream ammo-makers (Federal, Winchester) is in personal protection type ammo. Winchester offers a 200grn Big Bore 10mm @ a “box-flap” spec of 1175fps, most likely from a 5” factory test barrel fixture. If you recall, “200grns @ 1200fps” was the old Norma standard for that bullet-weight. Norma also used 5” test barrel fixtures.

Below is a link to this ammo on Midway’s site. If you scroll down to the review, the guy chronographed this load @ 1191fps using a 6” KKM barrel. That would likely mean the claimed velocity of 1175fps is legit from a 5” barrel. So a good “woods” or trail-type load.

Hornady did this too a couple of years back with its 180grn XTP load. Once spec-ed as a “full 10mm load” @ 1180fps from a 5” barrel, their 180grn XTP ammo is now listed @ 1275fps. While not a max load for that bullet-weight, 1275fps is definitely real 10mm territory.

Also ran some of this past the LabRadar.

Did a 40 shot string, Ruger SR1911 5in barrel:

• Avg velocity - 1200fps
• ES - 84fps
• SD - 21fps

It's definitely warmer than most FMJ offerings based on muzzle report and perceived recoil, unsure if it was the 1180fps or 1275fps spec.  

The date in the LabRadar file is 12/22/17, so would assume it's the older spec?

Yes, 2017-dated would likely be older spec for the Hornady 180gnr XTP.

We shot two 20-rd boxes of the new 180grn XTP/1275fps-rated just last week against a 20-rd box of the NOS load out of my stash rated @ 1180fps. (My buddy's 4.6" Gen4 G20 and my 5" Sig P220 Match Elite).

In both guns the difference in felt-recoil was noticeably significant but still controllable  - and actually, the new/hotter version @ 1275fps was more accurate at 15- and 25-yds than the NOS stuff. Hornady's website specifies this loads application as being for "personal defense" and hunting (medium-size game).
