Description
The Ultramax 9mm 147 grain round nose ammunition brings a heavier bullet option that trades some velocity for a noticeably softer shooting experience. As the heaviest commonly used bullet weight for 9mm, the 147 grain naturally runs at subsonic speeds, making it an ideal choice if you're running a suppressor or just prefer reduced recoil during longer range sessions.
These rounds feature powder-coated bullets, which offer some real benefits compared to bare lead or plating. The coating protects your barrel from lead fouling, shoots cleaner than uncoated rounds, and holds up well to high temperatures without melting or degrading. For reloaders, the Boxer-primed brass cases are perfect for reloading, giving you extra value after you run through these rounds.
Ultramax has been manufacturing ammunition since 1986 with a focus on quality at fair prices. They maintain high standards across their production, and as an added note, they're a registered law enforcement distributor for major brands like Winchester and Federal. This 50-round box comes packed 10 rounds per box (5 boxes per case), which is convenient for managing your ammo storage and range trips.
The round nose profile ensures reliable feeding in most modern pistols. Whether you're doing competition practice, building power factor loads, or just putting rounds downrange without feeling beat up by recoil, this is solid ammunition at a practical price point.

Frequently Asked Questions
Is 9mm 147 grain ammo good for subsonic or suppressed shooting?
Yes, the 147 grain weight naturally achieves subsonic velocities around 950-1050 fps, making it ideal for suppressed pistols. The heavier bullet also produces less muzzle rise and offers more consistent recoil control compared to lighter bullet weights, which is beneficial whether you're shooting suppressed or not.
What are the advantages of powder-coated bullets?
Powder-coated bullets provide excellent barrel protection by preventing lead fouling, shoot much cleaner than bare lead ammunition, and the coating remains stable even in hot conditions. The coating acts as built-in lubricity, so no additional case prep is needed, and these rounds work reliably in most modern pistols including those with polygonal rifling.
Can I reload the Ultramax brass cases?
Yes, these rounds come in new Boxer-primed brass cases that are perfectly suitable for reloading. This gives you extra value beyond the initial firing, as you can reload the cases multiple times before they wear out, which is especially practical for high-volume practice.
Will 147 grain 9mm cycle reliably in all pistols?
The round nose profile feeds smoothly in virtually all modern semi-automatic pistols. However, some compact or short-barreled handguns may need different overall length or may have magazines that prefer lighter bullets, so it's always smart to test feed a few rounds before committing to a full load.
How does 147 grain compare to lighter 9mm loads like 115gr or 124gr?
The 147 grain bullet produces noticeably softer recoil and runs at subsonic speeds, making it great for training and suppressed use. The tradeoff is that lighter bullets like 115gr and 124gr shoot flatter and reach higher velocities. The 147 is heavier so it's popular for competition power factor requirements and shooters who prefer less felt recoil.
Is Ultramax ammunition reliable?
Ultramax has been manufacturing ammunition since 1986 and maintains quality standards for sports hunting, range practice, and competitive shooting. They're a registered law enforcement distributor for major ammunition brands like Winchester, Federal, and CCI/Speer, which speaks to their credibility and production standards.
