Ask which caliber to stockpile first and you'll hear passionate cases for both: .22LR is the cheapest trigger time in existence, and 9mm is the round your serious guns actually eat. The right answer depends on what you own and why you shoot — here's the honest decision tree.
The case for .22LR first
Rimfire is the volume king. Per round, nothing touches it — a brick of Aguila Super Extra .22LR delivers 500 rounds of trigger time at a fraction of centerfire cost, in a package you can carry under one arm. It's the caliber of fundamentals: sight picture, trigger press, and follow-through without recoil masking your mistakes, plus it feeds everything from a kid's first rifle to your suppressed can host. If your shooting is skill-building, plinking, or small game, .22LR volume is the highest-return ammo money you can spend.
The asterisk: rimfire is historically the first caliber to vanish in demand panics and the slowest to return, because everyone's stockpile logic runs through it. That's an argument for buying your .22 reserve during calm markets, not a reason to skip it.
The case for 9mm first
9mm is the round of consequence. It runs your carry gun, your home-defense pistol, and probably your carbine — the guns whose proficiency actually matters. Practice with your defensive platform requires the caliber it fires; no amount of .22 volume substitutes for recoil management and manipulation reps on the gun you'd bet on. And as the world's most popular centerfire cartridge, 9mm is also the most liquid, most available, and most competitively priced centerfire round — a bulk 9mm case is the cheapest serious-caliber reserve there is.
The decision tree
- You own a defensive 9mm you're still building skill on: 9mm first. Proficiency on the gun that matters is the priority.
- You're teaching new shooters, training fundamentals, or shooting for fun on a budget: .22LR first — the volume advantage dominates.
- You own both platforms and shoot regularly: the honest answer is a split order — a case of each covers both jobs and one shipment amortizes the freight, per our shipping math guide.
Whichever you pick: verify the specific load runs in your guns before committing to the case — rimfire especially is picky about what individual firearms like. Our test-first guide covers the process.
The volume king by the brick
High-velocity .22LR in 500-round bricks is where trigger time gets cheapest.

Strip the tribal loyalties away and the .22LR case rests on one unbeatable fact: per dollar, nothing generates more repetitions. Trigger presses are the currency of shooting skill, and rimfire mints them at a rate centerfire can't approach. A shooter who runs a brick of .22LR through deliberate practice every month will out-improve a shooter burning the same budget in 9mm, because the rimfire shooter simply gets several times the reps — with less recoil noise drowning out the feedback each rep provides. If your goal this year is to shoot better, rimfire volume is the highest-yield purchase available.
The capability argument, stated fairly
The 9mm case rests on an equally stubborn fact: skill practiced on the gun you'd actually use matters more than skill in the abstract. Recoil management, follow-up speed, reloads under time, and confidence in your carry or home-defense pistol only build with the centerfire round it fires. And 9mm is the most commoditized centerfire cartridge on earth — the deepest supply, the most competitive bulk pricing, and the round that feeds pistols and carbines alike. When supply tightens, 9mm is also historically the caliber that recovers first, while rimfire — cheap to buy and cheap to hoard — is famously the first to vanish and the slowest to return. That asymmetry is a genuine argument for letting your 9mm reserve lead your rimfire reserve rather than trail it.
The both-and answer most shooters land on
The decision tree in this article resolves the "first" question, but the steady state for most people who own both guns is a ratio, not a winner. A common and sensible pattern: a deep rimfire reserve for skill volume, a working 9mm reserve sized to your defensive and range needs, replenished opportunistically when seasonal windows discount one or the other. Whichever you buy first, apply the same bulk discipline: prove the load in your gun — doubly important with rimfire, the most ammo-opinionated ignition system in common use — grade what you're buying against the quality ladder, and give the reserve proper sealed storage so year-five rounds fire like year-one rounds.
Frequently asked questions
Should I stockpile .22LR or 9mm first?
Buy .22LR first if your priority is skill-building volume and you own a rimfire trainer — nothing buys more trigger time per dollar. Buy 9mm first if your priority is feeding a defensive pistol and maintaining a serious reserve, since 9mm underpins most people's working guns and recovers fastest after shortages.
Does .22LR really disappear first during ammo shortages?
Historically yes. Rimfire is cheap enough to panic-buy in volume, production capacity is less flexible than centerfire, and it's often the last caliber to return to shelves at normal prices. A healthy rimfire reserve is best built during calm markets.
Is bulk .22LR reliable enough to buy by the case?
Quality bulk rimfire from major makers is broadly reliable, but rimfire is the most gun-sensitive ammo category there is. Test a few boxes of the exact load in your specific firearms before ordering a case — reliability varies more gun-to-gun than brand-to-brand.
