With over 7 million units sold since 1964, the Ruger 10/22 is the most popular rifle in America. It's the gun most people learn to shoot on, the gun most people take to the range for cheap fun, and — with the right ammo — a surprisingly capable small game and pest rifle.
The problem is that .22 LR is the most inconsistent cartridge on the market. Unlike centerfire ammo, rimfire .22 LR relies on a priming compound spun into the case rim, which means manufacturing tolerances matter enormously. One brand runs flawlessly in your 10/22. Another jams every third magazine. And the difference between them might be three cents per round.
We've compiled reliability data, accuracy results, and real-world community feedback to rank the most common .22 LR brands specifically in the Ruger 10/22 platform.

Detailed Reviews
1. CCI Mini-Mag 40gr — The one that always works
If you can only buy one type of .22 LR for your 10/22, buy Mini-Mags. CCI's clean priming compound, consistent rim thickness, and copper-plated bullet make this the most reliable .22 LR in semi-automatic rifles. Period. It's the benchmark everything else is measured against.
The copper plating serves two purposes: it reduces lead fouling in the barrel, and it feeds more smoothly than bare lead bullets — especially important in the 10/22's rotary magazine feed system. Mini-Mags also leave less residue in the action, which means fewer cleaning sessions between range trips.
The downside? They cost more than budget options — roughly $0.08/rd versus $0.05–0.06/rd for value brands. But when your gun runs 100% instead of 95%, those extra pennies buy a lot of peace of mind.
2. Federal AutoMatch 40gr — The accuracy contender
Federal developed AutoMatch specifically for semi-automatic rifles. It's slightly slower than Mini-Mag (1,200 vs 1,235 fps), but some 10/22 barrels produce tighter groups with it. Federal's 325-round bulk packs are one of the best values in .22 LR — consistent quality at near-budget pricing.
Every 10/22 barrel has its preferences. Some group tighter with Mini-Mags, others with AutoMatch. If accuracy matters to you (squirrel hunting, bench rest fun), buy a box of each and test from a rest at 25–50 yards. The difference can be significant — and the "winner" varies from rifle to rifle.
3. Aguila Super Extra 40gr — Best bang for the buck
Aguila's Super Extra punches above its price. Mexican-made, copper-plated, and priced closer to budget ammo while delivering near-CCI reliability. In comparative tests, it ranked #1 for price-to-performance. The 500-round bricks are competitively priced and the ammo runs well in 10/22s.
If you're a high-volume plinker who goes through 500+ rounds per range trip, Aguila Super Extra is the sweet spot. You get copper-plated reliability at bare-lead prices. The velocity spread (1,130–1,255 fps depending on lot) is wider than CCI's, but for plinking and casual shooting, it doesn't matter.
The BX-25 Magazine Problem
If you run the Ruger BX-25 25-round extended magazine, your ammo choice matters even more than with the standard 10-round rotary magazine.
The BX-25 has well-documented reliability issues: dimensional tolerance problems create excess play in the magazine well, the single follower spring has to serve 25 rounds (versus the rotary magazine's more consistent feeding geometry), and waxy-coated ammo increases friction against the magazine walls.
For BX-25 magazines: Stick to copper-plated ammo (CCI Mini-Mag, Aguila Super Extra). Avoid heavily waxed bullets like Remington Thunderbolt. The wax buildup on the magazine follower and feed lips causes the most common BX-25 jams.
The standard BX-1 10-round rotary magazine is significantly more reliable regardless of ammo choice. If you're using your 10/22 for anything where reliability matters (hunting, competition), use the factory 10-round magazine.
Best Subsonic .22 LR for Suppressed 10/22s
The 10/22 is one of the most popular suppressor hosts in America. Here's what works — and what doesn't.
| Load | Velocity | Cycles 10/22? | Noise (Suppressed) | Notes |
|---|---|---|---|---|
| CCI Standard Velocity 40gr | 1,070 fps | Yes | ~113.5 dB | Best all-around subsonic pick |
| CCI Suppressor 45gr | 970 fps | Yes | ~112 dB | Guarantees subsonic performance |
| CCI Quiet-22 Semi-Auto 45gr | 835 fps | Yes | ~110 dB | Quietest option that still cycles |
| CCI Quiet-22 40gr | 710 fps | No | ~108 dB | Will NOT cycle a stock 10/22 |
Important: Regular CCI Quiet-22 40gr (710 fps) will not cycle the bolt on a stock 10/22. You'll have to manually rack the bolt after every shot. If you want semi-auto function, use CCI Quiet-22 Semi-Auto (835 fps) or CCI Standard Velocity (1,070 fps).
CCI Standard Velocity 40gr is our top pick for suppressed shooting. At 1,070 fps, it's comfortably below the speed of sound (~1,126 fps at 68°F), which means no supersonic crack. It cycles the 10/22's action reliably, it's accurate, and it's affordable. At roughly 113.5 dB suppressed, it's quieter than a standard conversation at arm's length.
What to Avoid
Winchester M-22 — Worst in class
In comparative accuracy testing, Winchester M-22 produced 2.94-inch groups at 40 yards — the worst of all brands tested. It also has the most reported reliability problems in 10/22s. At the same price point as Aguila Super Extra, there's no reason to buy M-22.
Remington Thunderbolt — It works, but barely
Thunderbolt will cycle a 10/22, but it's the dirtiest .22 LR on the market. The heavy wax coating leaves residue in your action, your magazine, and your barrel. It's fine for a cheap afternoon of plinking if you clean your gun afterward, but don't use it in BX-25 magazines and don't expect great accuracy.
Any "Remington Bucket O' Bullets" variant
Remington's bulk loose-packed .22 LR has a reputation for inconsistency. Lots of duds, lots of misfires. Since Remington's bankruptcy and acquisition, quality control on their rimfire line has been hit-or-miss. You're better off with Aguila or Federal bulk packs at similar pricing.
Frequently Asked Questions
What is the best all-around ammo for the Ruger 10/22?
CCI Mini-Mag 40gr. It cycles reliably in virtually every 10/22 ever made, delivers consistent accuracy, and is available everywhere. If you can only buy one type of .22 LR, buy Mini-Mags.
Why does my 10/22 jam with certain ammo?
Most 10/22 jams are caused by ammo that's either too slow to cycle the bolt reliably (below ~1,050 fps), too waxy (causing feeding friction), or has inconsistent rim dimensions. Budget ammo like Remington Thunderbolt is more jam-prone than CCI or Federal due to looser manufacturing tolerances and heavy wax coating.
Is the BX-25 magazine reliable?
The BX-25 has well-documented issues: dimensional tolerance problems, excess play in the magazine well, and feeding friction with waxy ammo. The standard BX-1 10-round rotary magazine is significantly more reliable. If you use a BX-25, stick to clean, copper-plated ammo like CCI Mini-Mag.
What's the best subsonic .22 LR for a suppressed 10/22?
CCI Standard Velocity 40gr (1,070 fps) is the best all-around choice — reliably subsonic, cycles the action, accurate, and produces roughly 113.5 dB suppressed. CCI Suppressor 45gr (970 fps) guarantees subsonic performance. CCI Quiet-22 Semi-Auto 45gr (835 fps) is the quietest option that still cycles. Note: regular CCI Quiet-22 40gr (710 fps) will NOT cycle a stock 10/22.
How much .22 LR should I buy at once?
At current March 2026 pricing, bulk .22 LR runs about $0.05–0.06/rd in 500–5,000 round bricks. Buy in bricks of at least 500. If you shoot regularly, a case of 5,000 rounds offers the best per-round price and will last most shooters several months. .22 LR stores well for decades if kept cool and dry.
Can I shoot .22 Short or .22 Magnum in my 10/22?
.22 Short: Technically it will chamber in most 10/22s, but it won't cycle the action — you'd have to manually rack the bolt after each shot. Not recommended. .22 Magnum (.22 WMR): Absolutely not. .22 Magnum is a different cartridge with higher pressures. It requires a different gun, like the Ruger 10/22 Magnum variant (which has a different bolt and barrel).
