The .510 Whisper (13×47mm) is the second of two .50 in (13 mm) rounds developed by J. D. Jones with a specific focus on the Thumper concept and subsonic use. Based on the .416 Rigby case, it is a non-belted and bottlenecked cartridge.
External ballistics or exterior ballistics is the part of ballistics that deals with the behavior of a projectile in flight. The projectile may be powered or un-powered, guided or unguided, spin or fin stabilized, flying through an atmosphere or in the vacuum of space, but most certainly flying under the influence of a gravitational field.
Since the rifle was designed for use on Alaska's great bears, Johnson cut 720-grain (47 g) boat-tail .50 BMG bullets in half, seating the 450-grain (29 g) rear half upside down in the fireformed .50-caliber case. It didn't take Johnson long to find out that the truncated-shaped "solid" would shoot through a big brown bear from any direction ...

The McMillan TAC-50 is a manually operated, rotary bolt-action rifle. The large bolt has dual front locking lugs, and its body has spiral flutes to reduce weight. The heavy match-grade barrel, made by Lilja barrels, is also fluted to dissipate heat quickly and reduce overall weight, and fitted with an effective muzzle brake to reduce recoil.
Example of a ballistic table for a given 7.62×51mm NATO load. Bullet drop and wind drift are shown both in mrad and MOA.. A ballistic table or ballistic chart, also known as the data of previous engagements (DOPE) chart, is a reference data chart used in long-range shooting to predict the trajectory of a projectile and compensate for physical effects of gravity and wind drift, in order to ...
ArmaLite updated the rifle to the AR50-A1B model, which featured a smoother action and a more heavily reinforced muzzle brake. The newer bolt stop could be depressed by hand to release the bolt. The AR50-A1B was designed for long-range shooting, primarily firing the .50 BMG round. ArmaLite manufactures the rifle in several configurations:
Terminal ballistics is a sub-field of ballistics concerned with the behavior and effects of a projectile when it hits and transfers its energy to a target. Bullet design (as well as the velocity of impact) largely determines the effectiveness of penetration.
