180 Grain XTP 10mm

Starline cases, Winchester large Pistol primers, grains of Longshot

That’s great velocity for the 10mm. With the exception of Buffalo Bore, most factory 10s are in the 1050-1100fps range. Not much better than the .40S&W.

Should read 9 grains of Longshot

Thanks for sharing, you made my mind up for powder choice between AA#9 and Longshot.
What barrel length and firearm was this data from? I have a Springfield Ronin that has some upgrades and hoping for your velocity using the same components. We have an early doe season in September and my goal is to get one with my 10mm.

Mine is a Sig P220, 5" barrel

Second vote for longshot in a 10 mm

I load 155 grain barnes hollow points with a fair amount of longshot and get about 1600 ft/s out of a 6 inch STI high cap 2011

Actually that’s not true. Maybe back in 1998 it was, …. but welcome to 2025.

MagTech, Sig, and Fiocchi all load 180grn 10mm FMJ “range” ammo to 1250fps, which is hardly watered-down 40-level junk. You can attribute that to the Real 10mm Resurgence that’s been going on since circa 2003.

UW’ 180grn “Range Supply” is a bit hotter at 1270fps. I forgot exactly what S&B’s 180grn range ammo is spec-ed at, but l’m pretty sure it’s hotter than 1100fps.

A newer ammo company, Grizzly Cartridge Co., offers some really spicy 10mm ammo at max velocities, including a 180grn JHP at 1350fps.

To be fair, yes, there’s still .40-level factory “10mm” ammo to be found on store shelves (being “10mm” only on the box label, not in the ballistics). But most 10mm fans these days looking to enjoy shooting full-throttle factory ammo avoid those …. or they reload.

10mm Sig P220 Legion 5" barrel, 180 grain XTP on left, 180 Nosler on right. Shot into 20% Clear Ballistics Gel. Both loaded with 9 grains of Longshot. The XTP averaged 1295.1 FPS for 5 shots. I have not chronographed the Nosler as of yet.

Thanks for the data!

The XTP on the left weight 139.4 grains, the Nosler weighed 179.2 grains

I always appreciate 10mm data.

I'm still carrying my g40 on a chest rig with 200gr hard cast over power pistol powder. Gets the job done but it's a bit ungainly.

I need to see what I can push out of this little guy. Single six converted to a 5 shot 10mm.

I like the 180 XTPs in 10mm. I use a different load but I have found that to be an easy bullet to get good results from in the 10mm. Here's my hunting load and the cat I took with it.

Im getting about 1220 fps out of my 10mm 200gr JSP loads. Its fairly hot, but there are no pressure signs, and my Glock 20 handles it just fine.

The only reason I carry the G20 is "bear country".. so I purposefully went with as hot as my pistol and my hands could handle well..

Its certainly no oversized .40...
