What is the best long range rifle bullet? In this video, Rex compares long range rifle bullets such as the Berger VLD, Sierra Matchking, the Hornady A-Max and the Nosler LR Accubonds. If an ultra long range bullet is needed to maximize your maximum effective range, there is some new technology to consider. ULD bullet was developed during the Viet Nam era for both long range military sniper operations and later, applied to experimental bullets for Secret Service assignments. Some of the characteristics of Alco's ULD or Ultra Low Drag design were also incorporated in a similar but later development called the VLD or very low drag design. Both designs are equivalent for all practical purposes, except that the full ULD specification includes a rebated boattail design instead of the standard boattail (for about 15% gain in a accuracy by reducing muzzle-blast induced dispersion: the RBT step deflects most of the muzzle blast gas in a ring whereas the conventional BT tends to focus it into a ball in front of the emerging bullet, adding about 15% to the dispersion or random buffeting of the projectile.)
Alco's Ultra Low Drag or ULD bullets use both a rebated boattail and a 14-caliber secant with a .014-inch offset from tangent, to achieve minimum air resistance for a given weight and caliber.
Using the aluminum tip gives you approximately 0.50 thousandths longer bullet and will shift the weight to the rear of bullet and adds to the BC. The steel tip is used for thick skin animals and any rough service apps, like removing bullet from rifle several times a day. Steel tip work well if you have to have a shorter OAL bullet because some barrel twist rates won’t stabilize a longer bullet.
The Ultra Low-Drag design projectiles are very streamlined with a long nose and we use either mild steel or aluminum for the Ballistic Tip that intersects the body of the projectile. This does 2 things: One, it increases the Ballistic Coefficient of the projectile, and two it allows the tip to be pushed into the body of the projectile for maximum expansion when hunting game animals and is utterly devastating on Large Game.
The Rebated boat tail or (RBT) is a hybrid between the accurate flat base projectile and the long range stability of the traditional boat tail projectile. In turn, you get the best of both worlds, and when combined with the ULD design and longer ballistic tip, you get one of the most accurate projectiles.
Each Projectile is hand Swagged and not your ordinary assembly line projectile from the large competitors. Ultra match bullets are run on an ultra sonic concentricity machine for gyroscopic stability.
