Description
If you've spent time behind a .44 Magnum revolver, you know the 240-grain weight sits in that sweet spot for most barrels. It delivers the power you want while staying manageable, especially in shorter guns where energy matters more than velocity alone. Underwood loaded these with Hornady's XTP bullets, which have become the go-to for people taking big game with revolvers.
What Makes the 240gr XTP Stand Out
The 240-grain Hornady XTP is known for impressive balance. It expands reliably without coming apart, penetrates deeply to reach vitals, and groups well at the distances where revolver hunting actually happens. Real-world testing shows this bullet gets better terminal performance from mid-range revolvers than heavier loads, which means less velocity drop-off and more energy retention in practical scenarios.
Underwood's Nickel-Plated Cases and Flash-Suppressed Powder
These rounds use nickel-plated brass instead of standard brass. It chambers and ejects smoother, resists corrosion better during storage, and looks cleaner if you reload. The flash-suppressed powder keeps your night vision intact if you ever need the gun in low light. Underwood field tests everything in the guns their customers actually own, so you're getting ammo designed for revolvers people carry, not just lab conditions.
Realistic Ballistics and Field Use
You're looking at around 1350 feet per second and 971 foot-pounds of energy from typical revolver barrels. That's straightforward magnum power without the recoil hit of 300-grain loads. The rounds chamber reliably in full cylinders, and the XTP bullet itself has a reputation for performing across a wide range of velocities, which matters if your gun's barrel is shorter than you'd like. New production, non-corrosive, boxer-primed, and totally reloadable brass.

Frequently Asked Questions
Will the 240gr XTP work in short-barrel revolvers?
Yes. The 240-grain XTP was specifically chosen because it delivers solid performance from mid-range and even shorter barrels. Testing shows it maintains better energy retention from reduced barrel lengths than heavier loads, making it practical for compact carry guns.
Can I reload Underwood's nickel-plated brass?
Absolutely. The nickel plating actually makes reloading easier since it has lower friction than standard brass, which means smoother chambering and ejection through your dies. The brass is new production and fully reloadable.
What's the difference between the 240gr and heavier .44 Magnum loads?
The 240-grain load balances power and shootability really well. Heavier loads like 300-grain rounds pack more energy but with more felt recoil, making follow-up shots harder. The 240-grain tends to stay more neutral in the gun while delivering more than enough power for hunting.
Why does Underwood use flash-suppressed powder?
If you ever have to use your revolver in low light, regular powder can create a bright muzzle flash that ruins your night vision just when you need it most. Flash-suppressed powder minimizes that effect and keeps your eyes adapted to darkness.
