What is the difference between ammo grains?
As discussed in previous blogs, the grain of the round is the overall weight. Grain is a very small unit of measure — so small it takes more than a few hundred grains to add up to 1 ounce. So, the difference between a 115-grain round and a 124-grain round is the weight, sure.
How does grain affect ammo?
Lighter weight generally means more speed and distance, but also more recoil and less power at the target. Lighter bullets are good for competition and long-range shooting. Heavier weight generally means more effectiveness, making them excellent for defense, large game, and combat.
Do round nose bullets hit harder?
It’s a myth that round or flat noses on bullets increase their wallop over the slap of sharp-nosed bullets. The truth is just the opposite. Heavy bullets hit harder, but not necessarily blunt ones.
What grain is better for 9mm?
For self-defense, shoot your specific 9mm handgun with 115 grain and with 147 grain bullets at 25 yards and less to see if you find, like I did, that the heavier 147 grain bullet hits the target higher almost every time.
Is 115 grain ammo good for self-defense?
While this particular cartridge is offered in various configurations, the most common is the 115 gr. full metal jacket (FMJ). This is an excellent round for practice, matches and informal “plinking.” However, it is a terrible choice for self-defense because of its penetration capability.
What are flat point bullets used for?
Flat Point Jacket (FPJ) bullets are actually FMJ bullets with a flat nose. These bullets are designed to improve the stopping power of the FMJ bullets. They are suitable primarily for revolver ammunition but are also used in pistol ammunition.
What is Wadcutter ammunition used for?
A wadcutter is a special-purpose flat-fronted bullet specifically designed for shooting paper targets, usually at close range and at subsonic velocities typically under approximately 900 ft/s (274 m/s). Wadcutters have also found favor for use in self-defense guns, such as .
What does JSP mean in ammo?
A soft-point bullet is intended to expand upon striking flesh to cause a wound diameter greater than the bullet diameter. Jacketed soft point bullets are usually abbreviated JSP in the ammunition and reloading industry.
Why are FMJ used in war?
The use of full metal jacketing in military ammunition came about in part because of the need for improved feeding characteristics in small arms that used internal mechanical manipulation of the cartridge in order to chamber rounds as opposed to externally hand-reloading single-shot firearms.
