Mag. They are also made with the longest possible hybrid ogive and are a tad bit heavier than common bullet weights associated with each caliber. When comparing BCs of different bullets, it is important to use an apples-to-apples approach. Inspired by Bob Beck, the host of the TV show Extreme Outer Limits, the Berger EOL was designed by noted ballistician and bench-rest shooter Bryan Litz. USA -(Ammoland.com)-Heres why obscure [and some say boring] bullet ballistic concepts like ballistic coefficient and sectional density are essential if you want to hit targets regularly when shooting at long-ranges. Enjoyed your discussion on BCs. 2023 Outdoor Sportsman Group. With modern ammunition, we are seeing higher ballistic coefficients such as the ridiculously high BC of the. For example, a lead round-nosed bullet can sure pack a punch! The 55-grain bullet provides a good balance between the light 40-grain and the heavy 77-grain bullets. Now, to save you the time and effort I put in, Im going to share just about everything I know about ballistic coefficient. Also notice the big difference in BC between the round nose bullet (.216) and the spire point bullet (.357). I shoot a variety of fire arms and have hunted and shot competitively for .quite a few years. Select what level shooter you are! If they penetrate only 12 or 14 inches (inhibited by that same massive frontal diameter that's causing such dramatic tissue destruction), that's usually adequate. Ballistic Coefficient is essentially a measure of air drag. These variables, which well discuss in the next column, can change each time and location you shoot. you a link to reset your password. For this example, I am going to use a Hornady 30-06 Springfield load with a 125 grain SST projectile, found here.

Some of the data that are collected include the number of visitors, their source, and the pages they visit anonymously. It has a better trajectory than the lighter 36-grain and 40-grain bullets. Learn how your comment data is processed. Heres what you need to know about drag models. Technically, its the ratio of the weight to the surface area, but its easier to think in terms of diameter as thats how bullets are measured. As opposed to same in a flat base bullet. Now imagine a nail flying point first. Weight retention (175.9 grains) was a remarkable 98 percent, and the expanded bullet measured 0.69 inch, actually larger than at 50 yards. If you are looking to hit a target beyond 600 yards, your really need to learn and understand your rounds BC. This is because the value for the shape of the bullet is determined by how close its shape is to the drag model. A cookie set by YouTube to measure bandwidth that determines whether the user gets the new or old player interface. Gain a deep knowledge of ballistic science and access our improved ballistic calculator. My best "take away" was the reinforcement of consistency in long range shooting. Fluid properties (air) vary with velocity and environment. Now, lets launch them both at 2,750 feet per second from a Sierra Bullet Blaster 7000 rifle and see what happens. I may earn a small part of the sale from links to any products or services on this site. The G7 drag model, which is gaining popularity, is based off of a more aerodynamically shaped options with a boat-tail base (it tapers back). Thats where it started, and since then its gone from simple experiments all the way to engineers and scientists at places like Aberdeen Proving Ground working to improve ballistic calculations. It's often been compared to the 6.5 Creedmoor. While the ELD-Match is made for competition, the ELD-X is built for killing. I want this to be the best ballistic trajectory calculator out there. To do this, bullets should be compared at a given Mach number (e.g. A high BC bullet can maintain velocity better than a low BC bullet under the same conditions. Luckily, there are, G1 or Ingalls (flat base with 2 caliber (blunt) nose ogive by far the most popular), G5 (short 7.5 boat-tail, 6.19 calibers long tangent ogive), G6 (flat base, 6 calibers long secant ogive), G7 (long 7.5 boat-tail, 10 calibers tangent ogive, preferred by some manufacturers for very-low-drag bullets), G8 (flat base, 10 calibers long secant ogive). The new Tipped MatchKing is living up to that legacy. Personalize your experience. #4. Until now. AccuBond at 2600 fps. But the more streamlined bullets have a higher ballistic coefficient.
