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.
