Browning .22LR 45gr Subsonic LRN Ammunition - 100 Rounds (20 Packs)

Browning .22LR 45gr subsonic LRN ammunition delivers reliable performance in rimfire handguns and rifles where you want reduced noise signature without sacrificing function. This is serious ammo for shooters who prioritize stealth—whether you're plinking on a quiet range, training in a suppressed setup, or hunting small game where sound discipline matters. At 45 grains and subsonic velocity, these rounds stay subsonic, meaning they don't crack the sound barrier and won't produce the sharp supersonic snap you get from standard .22LR loads. Browning engineered these cartridges with precision manufacturing and quality control to feed reliably and shoot accurately shot after shot. You're getting 100 rounds per box, packaged as 20 smaller packs—convenient for range sessions or stashing backup ammo in different locations.

The 45-grain lead round nose (LRN) bullet is a proven design: it feeds cleanly through most .22 platforms, and the modest weight helps maintain that subsonic character while delivering consistent accuracy downrange. This isn't match-grade target ammo, but it's built to work—no duds, no jams, no excuses. If you're running a .22 suppressor or just want quieter shooting without the report, subsonic .22LR is the smart choice.

Browning's reputation in ammunition manufacturing means you're not gambling on consistency. These rounds come from a company that understands what shooters and hunters actually need: ammo that goes bang, performs as advertised, and doesn't leave you stranded. Keep a box in your truck, your range bag, or your kit—100 rounds of solid, dependable rimfire.

Frequently Asked Questions

Will Browning subsonic .22LR work in my .22 rifle or handgun?

Yes. These .22LR cartridges are standard rimfire rounds and will chamber and fire in any .22LR-chambered firearm, whether rifle or handgun. The subsonic velocity means the bullet travels slower than the speed of sound, producing less noise.

What's the difference between subsonic and standard .22LR ammunition?

Subsonic .22LR rounds travel at velocities below approximately 1,125 fps, so they don't create a supersonic "crack" when fired. This makes them ideal for suppressed shooting, quiet range sessions, or situations where noise discipline matters. Standard .22LR is typically faster and louder.

Can I use subsonic .22LR in a suppressed .22?

Yes. Subsonic ammunition is the optimal choice for suppressed .22LR firearms because it eliminates the supersonic crack entirely, resulting in the quietest possible shot. Standard .22LR in a suppressor will still make noise from the bullet breaking the sound barrier.

What does the lead round nose bullet do?

The LRN (lead round nose) design is a classic, reliable bullet profile that feeds smoothly through rimfire chambers and magazines. It also provides consistent, predictable performance suitable for general shooting and small-game hunting.
