Name the gun and IronScout works out the caliber. Say what it's for and it changes the order. It marks anything it assumed, and lets you correct it.
Ask in plain English. We'll show you how we read it.

This changes the order results come back in — not which ones you see.
Your Gun Locker
Add your firearms once. Switch on “Gun Locker calibers only” to limit a search to the calibers in your locker, and get price-drop and back-in-stock alerts.
Most ammo search engines stop at price lists — sorted by cost per round and nothing else. That works when you already know exactly what you want. But choosing between range ammo for a weekend class, hollow points for carry, and match-grade loads for competition are fundamentally different decisions with different priorities. IronScout is an ammunition search engine built around that reality.
Name the gun instead of the cartridge and IronScout works out the caliber, then tells you it guessed and which of your words caused it — one click drops the assumption. Brand, grain, bullet type, case material and bulk are read out of the same sentence and enforced as filters. Say what the ammo is for and it changes the order results come back in, not which results you see.
Add the guns you shoot and the Gun Locker knows their calibers. Switch on “Gun Locker calibers only” to limit any search to those calibers; leave it off and the Gun Locker does not touch your search — we never narrow results on what you own unless you ask. Watch the products you care about for price-drop and back-in-stock alerts.
Ammo prices shift constantly. IronScout tracks price history for every product so you can see whether today's price is a genuine deal or just normal. Set price drop alerts and back-in-stock notifications to stay informed without manually checking retailer sites every day.

We built what we wished existed.
IronScout is an indexing and intelligence layer. We don't sell ammo, intermediate checkout, or compete with retailers. We help you understand what's available and where.
See how prices have changed over time for any product. Historical context helps you understand whether today's price is actually good or just normal.
Looking for range ammo? Defense rounds? Match-grade precision? IronScout surfaces results based on what you're actually trying to do, not just the lowest sticker price.
No recommendations, no "best deals," no urgency tactics. IronScout provides information and context. The decision is always yours.
Add your firearms to the Gun Locker, and “Gun Locker calibers only” limits a search to those calibers. It is a switch you flip, not a guess we make — leave it off and the Gun Locker does not touch your search.
Get notified when prices drop or items come back in stock. No spam, no manufactured urgency—just the changes that actually matter to you.
When something is promoted or paid, it's clearly labeled. Relevance and accuracy come before monetization.
IronScout exists because we wanted something better for ourselves. We understand the frustration of endless tabs and price-checking because we lived it.
From searching to buying with confidence
Describe what you need in plain language: a caliber, plus brand, grain, case material, bullet type, or what you are shooting it for. IronScout narrows on the specifics you state — and where a product has no recorded value for one of them, it keeps the product and labels it unverified rather than dropping it. A stated use changes the ordering only, and applies no filter of its own.
Found something worth watching? Save it to your watchlist. IronScout monitors prices and availability across retailers in the background and notifies you when something changes — a price drop, a restock, or a new deal on a product you care about.
When conditions are right, click through directly to the retailer’s product page. IronScout never handles checkout, payment, or shipping. You buy direct, and you keep whatever loyalty points or promotions the retailer offers.
Everything you need to know about searching and comparing ammo prices.
IronScout is a free ammunition search engine that compares prices across multiple online retailers. It tracks real-time availability, price history, and price-per-round for 23 calibers — from 9mm and 5.56 NATO to .308 Winchester and 12 gauge. Think of it as a flight search engine, but for ammo.
IronScout indexes product listings from tracked online ammunition retailers. Prices, availability, and product details are refreshed regularly so you can compare current observed market data without visiting each store individually.
Yes. Searching and comparing ammo prices is free with no account required. A free account unlocks the Gun Locker and alerts. Premium is not offered in v1.
No. IronScout is a search and comparison tool, not a retailer. When you find what you're looking for, you click through to the retailer's site to purchase directly. We never handle payment, shipping, or inventory.
Most ammo search engines want a caliber and sort the matches by price. IronScout reads a plain-English sentence: name your rifle or pistol and it works out the caliber, pulls brand, grain, bullet type, case material and bulk out of the same sentence and enforces those as filters, and takes a stated use — range, home defense — as a reordering rather than a filter. It then shows you exactly what it understood, marks anything it assumed rather than read, and lets you drop any assumption. Tracked price history shows how today’s price compares with what we have recorded, so you can judge it yourself.
IronScout currently tracks 23 calibers including 9mm, 5.56 NATO, .223 Remington, .308 Winchester, .22 LR, .45 ACP, .380 ACP, .40 S&W, 10mm Auto, .300 Blackout, 6.5 Creedmoor, 7.62x39, .30-06 Springfield, 12 gauge, .357 Magnum, .38 Special, .44 Magnum, 20 gauge, .243 Winchester, .270 Winchester, .30-30 Winchester, .17 HMR, and .410 bore. More calibers are added based on demand.
Set a target price or choose to be notified on any price drop for products you care about. IronScout monitors prices daily and sends you a notification when conditions are met. You can also set back-in-stock alerts for items that are currently unavailable.
