I’ve used these bullets in my .284 rifle for several seasons. They offer excellent accuracy and consistent performance. The polymer tip ensures reliable expansion without overpenetration. Great for varmints and medium game. Handloading is straightforward with proper data.

The bullets are well-made and fit perfectly in my chamber. I’ve loaded them with a proven recipe and saw consistent groupings. The boat tail design helps with long-range shots. Slightly more expensive than standard bullets, but worth it for performance.
