A bull moose needs a bullet that can hold together and penetrate deeper than a bullet that is going to be used for whitetail. Introducing the latest products from the worldwide leader in ammunition. The minimum SD for hunting large game is .250. New reloading data must be opened as a PDF document in an up-to-date compatible PDF viewer. If the bullet passes through cleanly, remaining relatively intact, not all of the energy is transferred to the target. It still has more penetrating power than lighter weapons such as general-purpose machine guns, though it is significantly heavier and more cumbersome to transport. Be aware you may consider some of them unusable. The bullet type and powder make the recoil force different between bullets. Unsubscribe at any time. I want this to be the best ballistic trajectory calculator out there. Velocity is key for proper penetration and expansion, which is critical for hunting. For a lot of cartridge comparisons we have done, recoil is usually not that huge of an issue. But, if you need the performance, its just something you have to deal with, especially if you dont reload. KelTec Sub 2000 [Review]: Best PCC Firearm?

The 50 BMG (Browning Machine Gun) is a large 50 caliber cartridge packing some serious long-range firepower in a 12.7 x 99mm NATO round. As the 50 BMG bullet has a high ballistic coefficient, it is used for powerful sniper rifles. A high number means the bullet is more efficient at resisting air friction (negative acceleration). Coming up on wounded animals, especially if they are predators, can be dangerous and being able to drop them cleanly takes this risk away. The less a bullet drops during its flight, the easier it is to make adjustments for longer distance shots. The biggest issue we have with the 50 BMG is the sheer weight of the rifle. Retail Price: $478.50. To measure the ballistic coefficient, we need the BC projectile that is equivalent to the ballistic coefficient in a point mass trajectory of below 20 degrees. Almost all rounds have a ballistic coefficient of less than 1.0, but large rounds like the 50 BMG can exceed this normal BC. It is still a good idea to check legality before making a purchase.

Hornady Match rifle ammunition is loaded with the most accurate, consistent match bullets in the world, featuring our AMP bullet jackets. Due to the high ballistic coefficient of the bullet, the .50 BMG's trajectory also suffers less "drift" from cross-winds than smaller and lighter calibers, making the .50 BMG a good choice for high-powered sniper rifles. The trajectory is what just about every hunter or competitive shooter of every skill level will be interested in when comparing two different cartridges. .338 Lapua Mag vs .50 BMG Cartridge Comparison. This calculator will produce a ballistic trajectory chart that shows the bullet drop, bullet energy, windage, and velocity. It can shoot up to ranges of 330 yards and floats in the air for about seven seconds, before dropping to the ground. Of course, looking at averages might not be fair as there are .338 LM rounds that carry similar or even higher velocities than some 50BMG rounds.

The ballistic coefficient is derived from an equation that uses several bullet and cartridge variables. The two most important variables are the Initial Velocity and the Ballistic Coefficient. Since a 50 cal bullet can slice through a body without protective armor, it can also kill someone. (We'll get to the meaning of "G1" in a moment.) [32] Applications requesting firearms in this caliber are assessed by the same criteria as smaller calibers; with the applicant having to prove they have a valid reason for owning such a weapon.

It is inversely proportional to the negative acceleration a high number indicates a low negative acceleration. For the .338 LM, we recommend the Nosler Trophy Grade AccuBond 300gr round. In ballistics, the ballistic coefficient (BC) of a body is a measure of its ability to overcome air resistance in flight. While the .338 rounds have a much smaller diameter than the huge .50 cal rounds, the exponentially heavier bullet weights of the 50BMG rounds make up for the large size. This e-mail address is already subscribed. But, one can also survive the wound from a 50 BMG shot if it isnt fatal.

He wanted the round to be used in a machine gun, and wanted the machine gun to be based on a scaled-up version of the M1917 Browning. To do this, we have selected several rounds for each cartridge we are comparing. As the 50 BMG bullet has a high ballistic coefficient, it is used for powerful sniper rifles. FMBT bullets. This is why they fit perfectly to any automatic or belt-fed snipers, machine guns, or pistols designed for this cartridge. It boasts a BC of 0.874, and some indicators point to a 0.900 BC at 2,900 fps. By adding trajectories to the panel on the right you may produce charts and graphs that show the different trajectories side by side. From the bullet seating to the optimal charges and velocities, Hornady Match ammunition is designed to live up to company founder, J.W. [4], The development of the .50 BMG round is sometimes confused with the German 13.2mm TuF, which was developed by Germany for an anti-tank rifle to combat British tanks during WWI and against aircraft.
