Hornady ECX .224 50gr Monolithic Hunting Bullets x50
The Hornady ECX (Extreme Copper alloy eXpanding) is a monolithic hunting bullet designed for handloaders seeking controlled expansion and reliable terminal performance. Machined from a copper alloy rather than a traditional jacketed-lead construction, the 50-grain .224-diameter projectile expands consistently across a wide range of impact velocities.
Hornady engineered the ECX with particular attention to compatibility with traditional European chamber dimensions, making it well suited for Continental-spec rifles as well as standard .223 Rem and .22-250 Rem chambers. The optimised profile delivers high levels of accuracy across varied twist rates, so handloaders working with anything from a 1-in-12 twist classic varmint rifle to a faster-twist precision barrel will find reliable consistency.

Yes, the ECX bullet is designed to perform reliably in standard .223 Rem and .22-250 Rem chambers, as well as Continental-spec rifles.
Does the bullet perform well in different twist rates?
Yes, the optimized profile ensures reliable accuracy and consistent performance across a range of twist rates, from 1-in-12 to faster twist barrels.

I’ve been using these bullets in my .223 Rem for several months now. The expansion is consistent and the accuracy is excellent. No issues with feeding or chamber compatibility. Great for varmint hunting and small game.

The bullets are easy to load and perform well in my 1-in-12 twist rifle. I noticed a slight improvement in terminal performance compared to traditional lead bullets. Slightly more expensive, but worth it for reliability.

Used these in a Continental-spec rifle and they fit perfectly. No problems with expansion or accuracy. The copper alloy construction feels more durable and the bullet performs predictably at different velocities.
