Description
Underwood's Range Supply line brings consistent, quality ammunition to the range at a price point that makes frequent practice realistic. This 10mm load uses a full metal jacket flat nose bullet that won't expand on impact, making it ideal for target shooting where you want reliable feeding and predictable performance without expansion concerns.
What Makes This 10mm Load Work
You get the ballistics people expect from a serious 10mm round without paying for features you don't need on the range. The 180-grain bullet weight sits in the sweet spot for the cartridge, delivering good velocity without excess recoil. At 1250 feet per second, this load will cycle through semi-automatic pistols reliably and give you the ballistic performance that makes 10mm worth shooting. The flat nose profile helps the bullet maintain a nose-forward orientation through intermediate barriers, which is one reason this design has stayed popular for decades.
Quality Components Built to Last
Like all Underwood ammunition, this comes loaded with flash-suppressed powder that won't compromise your vision in low-light shooting. The brass cases are boxer-primed and reloadable, which means you can get a second life out of your brass if you handload. New production, non-corrosive ammunition means no surprises during cleaning, and the cases cycle smoothly through your magazines and chambers. Underwood field-tests their loads in real firearms under real-world conditions, so when you buy this ammo, you're getting something that's actually been shot through guns like the ones in your safe.

Frequently Asked Questions
Is this Underwood 10mm FMJ good for range training?
Yes, this is exactly what it's made for. The full metal jacket bullet won't expand, feeding is reliable, and the muzzle velocity puts it in the middle of the 10mm performance range without being overloaded. You get quality brass cases that won't slow you down at the range, and they're reloadable if you handload later.
What's the difference between the flat nose and round nose FMJ?
The flat nose profile helps the bullet maintain better penetration through harder materials because it stays nose-forward. For range shooting, the difference is mostly academic. The flat nose is the more common design in modern 10mm practice loads and works reliably in semi-automatic pistols.
Can I reload the brass cases from this ammunition?
Yes. These are new production, boxer-primed brass cases, which is the standard for reloading. Once you shoot them, you can process and reload them like any other quality brass ammo. That's one reason many people choose Underwood for their practice rounds.
How does this compare to lighter 10mm loads?
The 180-grain bullet is one of the heavier common weights for 10mm practice ammo, which means slightly more recoil than a 155 or 165-grain load, but also better energy retention at distance. At 1250 fps this isn't a magnum-level hot load, but it's standard full-power 10mm performance that will give you realistic practice.
