What is the advantage of boat tail ammo?
Advantages of Boat Tails A boat tail raises a bullet’s ballistic coefficient. That’s essentially a number that reflects how well an object overcomes air resistance. Because the feature makes a bullet a little more accurate at long range, it is only found in rifle rounds.
Are boat tail bullets more accurate?
It is one of the most accurate boattail bullets on the market. Because of its size, manufacturing tolerances are a smaller percentage of the overall bullet, and affect accuracy less. Boattails increase the ballistic coefficient of bullets, which helps them overcome air resistance and wind deflection.
What is the difference between boat tail and FMJ?

When were boat tail bullets invented?
The spitzer bullet design was first introduced in 1898 as the Balle D by the French Army. The Balle D bullet was designed by Captain Georges Raymond Desaleux, in order to improve the ballistic performance of the existing French 8×50mmR Lebel service cartridge of 1886.
What is ball ammo used for?

Are BTHP good for self-defense?
The BTHP is designed for rapid expansion and fragmentation, causing massive wound trauma on target without overpenetration. As a result, this cartridge is a great round for home or personal defense in highly populated urban settings.
