This barrel is specifically engineered for AAE_243 / 6mm (.243) caliber, giving you a rock-solid foundation for a wide range of popular 6mm cartridges, depending on the chamber your gunsmith cuts (such as .243 Win and other 6mm wildcats). Frisco Guns+2ammunitionsforsale.com+2
If you’re planning a new varmint rifle, a do-it-all .243 hunting rig, or a precision-oriented 6mm bolt gun, starting with this Douglas blank puts real accuracy potential at the core of your build.
#2 Contour – Versatile Medium Sporter Profile
The #2 contour is a classic medium-sporter style that offers a smart balance between barrel stiffness and carry weight: Frisco Guns+2Primary Tactical+2
Heavier and stiffer than ultralight “mountain” contours for improved consistency as the barrel heats.
Lighter than heavy varmint or bull profiles, making it well-suited to field carry and practical hunting.
Approximate blank weight around 2.90 lb, giving you a finished rifle that handles naturally without feeling nose-heavy. Frisco Guns
For shooters who want one barrel that can hunt all day and still group tight from the bench, the #2 contour is an ideal middle ground.
