Range and Bulk Ammo
White Box
The Winchester White Box 223 55 Grain FMJ 1,000 Round Case is the go-to for high-volume shooting. It’s brass-cased, non-corrosive and comes in a full case. Buying by the case cuts down on trips and keeps your lots consistent.
The White Box 45 Grain JHP is a lighter, faster option at 3,600 fps. It’s a fun plinking and pest load.
Target and Practice, USA Ready
The Target and Practice 62 Grain FMJ gives you a heavier bullet for rifles with faster twist rates. The USA Ready 62 Grain Open Tip uses a match-style open tip. Open-tip match bullets often group tighter than basic FMJ.
Varmint and Predator
For prairie dogs, groundhogs and coyotes, pick a polymer tip.
- Varmint X 55 Grain Extreme Point: lists 3,240 fps. Fast expansion and a flat path.
- Ballistic Silvertip 55 Grain Varmint: a premium tipped bullet with the same listed speed.
- Universal Varmint and Target 1,000 Round Case: a polymer tip in bulk. It’s handy for long prairie dog days and range work alike.
Hunting Loads
Where state law allows 223 for deer, the 64-grain loads make the most sense. Heavier bullets hold together better and push deeper.
- The Deer Season XP 64 Grain Extreme Point uses a large polymer tip for fast expansion. It lists 3,020 fps and 1,296 ft-lbs.
- The Super X Power-Point 64 Grain is a classic soft point. It’s a simple, old-school design many hunters still trust for close shots.
- The Super X 55 Grain Soft Point 200 Rounds is a budget soft point for coyotes and hogs.
Rules on using 223 for big game vary a lot by state. Some ban it for deer. Check your local regulations before the season.
Defense and Match
Silvertip Defense
The Silvertip 64 Grain Defense Tip is Winchester’s 223 defense load. It lists 2,700 fps and 1,036 ft-lbs. The polymer tip helps the bullet open and resists plugging. Laws on defense ammo vary, so check your state and local rules.
Match
The Winchester Match 69 Grain Sierra MatchKing is the precision pick. It lists 3,000 fps and 1,379 ft-lbs. The 69-grain MatchKing shoots well in most 1:7, 1:8 and 1:9 twist barrels. It’s a smart choice for target matches or anyone chasing small groups.

One last tip: 223 Remington ammo is safe in 5.56 and 223 Wylde chambers. Firing 5.56 in a rifle stamped only 223 Remington is not advised. Check your rifle maker’s guidance. Our Winchester 5.56 ammo guide covers the 5.56 side of the lineup. For another view, see the Hornady 223 ammo guide.

Frequently Asked Questions
Is Winchester White Box 223 good ammo?
White Box is brass-cased, non-corrosive range ammo made for volume shooting. It is a common choice for practice, training classes and plinking. For tight groups at long range, step up to a match load. For hunting or defense, choose an expanding bullet.
Can I shoot 223 in a 5.56 rifle?
Yes. A 5.56 NATO or 223 Wylde chamber safely fires 223 Remington ammo. Going the other way, firing 5.56 ammo in a rifle marked only 223 Remington, can raise pressure and is not advised. Check the stamp on your barrel and your rifle maker’s manual.
What is Winchester Deer Season XP 223 used for?
Deer Season XP uses a 64-grain Extreme Point bullet with a large polymer tip for fast expansion on deer-size game. It is meant for hunters in states that allow 223 for deer. Check your state’s rules first, and keep shots at modest range.
What is the difference between Varmint X and Ballistic Silvertip?
Both are polymer-tipped varmint loads built for fast expansion on small game and predators. Varmint X uses Winchester’s Extreme Point bullet. Ballistic Silvertip is a premium tipped bullet. In our catalog, both 55-grain loads list the same velocity, so try both and see which groups better.
