A working inventory for a shooter who splits time between a rimfire plinker, an AR-15, a varmint rifle, and a pocket pistol easily spans ten distinct ammunition categories. No single brand covers every need, which is why a serious ammo locker typically mixes major-loader staples (Winchester, Federal, CCI) with specialty brands (Aguila for low-cost rimfire, Lapua for match-grade). This guide works through ten categories with brand-specific context for each.

Brand-Specific .223 Remington

For AR-15 and bolt-action .223 shooters who prefer a single-brand supply chain, winchester 223 ammo in USA White Box 55-grain FMJ, Super-X 64-grain, and Varmint X 40-grain covers training, general hunting, and varmint work from one brand family. Lot-to-lot consistency has been a long-standing Winchester strength.

The 22 Long Rifle Landscape

High-volume 22 LR shooters typically buy 22 shells bulk in 525-, 1,000-, or bucket-packaging quantities. Bulk per-round cost on 22 LR sits at $0.06 to $0.12 for quality brands, making it the cheapest practical cartridge for sustained range use.

Within the 22 LR brand spectrum, aguila 22lr from Mexico covers the budget-to-mid tier with offerings like Interceptor high-velocity, Super Extra standard, and Sniper Subsonic 60-grain — the heaviest commercially produced 22 LR bullet in current production.

For reliability-critical applications, cci 22lr Mini-Mag and Standard Velocity remain the consensus choices among semi-auto pistol shooters who need consistent cycling from Rugers, Browning Buck Marks, and S&W Victorys.

Volume competition and range shooters gravitate to federal 22lr ammo Automatch 325-round boxes and Champion 525-round packs for sustained-fire practice at consistent per-round pricing.

At the premium match tier, lapua 22lr Center-X and Midas+ dominate competitive smallbore and PRS rimfire, with lot-selected offerings that consistently produce sub-½-MOA 50-yard groups from quality match rifles.

For general-purpose sporting, hunting, and plinking, winchester 22lr ammo in Super-X 40-grain LRN and Power-Point 40-grain JHP covers small-game and casual range use at accessible pricing.

Modern Intermediate Centerfire

Introduced by Federal in 2017, 224 valkyrie ammo pushes a 90-grain Sierra MatchKing at 2,700 fps to deliver supersonic performance out to 1,300+ yards — the first AR-15-platform cartridge to maintain supersonic flight past the 1,000-yard mark.

The Venerable .243 Winchester

The 243 ammo category remains one of the most popular dual-purpose cartridges in U.S. hunting. A 95-grain load at 3,100 fps covers deer-sized game; an 80-grain at 3,350 fps handles coyote and predator applications.

The Pocket Pistol Cartridge

Though overshadowed by .380 ACP in modern pocket-gun design, 25 acp ammo remains in active production from Hornady, Winchester, and Fiocchi for shooters carrying heritage Baby Brownings, Berettas, and Colt Junior pistols.
