Description

Federal 243 Win 90gr ELD-X ammunition loads a 90 grain ELD-X bullet into the 243 Winchester. Federal lists a muzzle velocity of about 3150 feet per second and a ballistic coefficient of .409, which works out to roughly 1983 foot-pounds of muzzle energy by standard calculation. Each box holds 20 rounds.
Long-Range Accuracy That Still Hits Hard
The ELD-X bullet is built for hunters who want match-grade accuracy with dependable terminal performance. Federal highlights its extremely high ballistic coefficient, which helps it hold velocity and resist wind drift at long range.
A polymer tip that resists deformation keeps the bullet flying consistently and starts expansion even at the lower velocities found at long range. Behind the tip, a concentric copper jacket and robust shank help the bullet hold together for penetration up close.
Federal loads heavy-for-caliber ELD-X bullets to get the most out of each cartridge, so you get a flat-shooting load that still carries plenty of energy into game.

Hunting Tips
Use Federal 243 Win 90gr ELD-X ammo only in rifles chambered for 243 Winchester.
Zero your rifle with this exact load, then confirm your holds at the longest distance you expect to shoot.
Aim for the heart and lung area on a broadside or slightly quartering animal for quick, ethical results.
Practice from field positions such as sitting, kneeling and shooting off sticks before the season.
Federal 243 Win 90gr ELD-X ammo is a flat-shooting choice for hunters after deer, pronghorn and other medium game.
The 243 Winchester is a favorite for deer and pronghorn because it shoots flat and recoils lightly. A 90 grain ELD-X is a heavy bullet for the cartridge, which gives Federal 243 Win 90gr ELD-X ammo more retained energy at longer distances than lighter varmint bullets.
Before the season, shoot a few groups with Federal 243 Win 90gr ELD-X ammo from a solid rest, then practice from the positions you will actually hunt from. A rifle that groups well off the bench is only part of the picture; being able to hold steady from sitting, kneeling or off shooting sticks is what fills tags.
After the shot, give the animal time before you follow up, and mark where it was standing. A soft point bullet that does its job usually leaves a good blood trail, but patience makes recovery much easier.
Clean your rifle after the hunt and store it with a light coat of oil, especially if it was out in rain or snow.
Premium hunting ammunition costs more than practice loads, so many hunters zero with a box of the same load they will hunt with and then confirm their dope before each season. Buying several boxes of Federal 243 Win 90gr ELD-X from one lot keeps your point of impact consistent from year to year.
Wind and range estimation matter as much as the bullet. Use a rangefinder, learn how your load drifts in a crosswind, and practice at the distances you expect to shoot. Store ammunition in a cool, dry place in its original box so it performs the same on opening day as it did at the range.
