Is More Grain Better in Ammo?
The age-old question among firearm enthusiasts: "Is more grain better in ammo?" The answer to this inquiry is not straightforward, and it’s a topic of ongoing debate in the world of firearms. In this article, we’ll dive into the nitty-gritty of bullets and bullets’ grains to provide you with a clear understanding of what makes them tick (or not tick).
**What are Grains of Bullets?**
Before we delve into the pros and cons of more grain ammo, it’s essential to understand what grains of bullets refer to. Bullets come in various shapes and sizes, but most commercial loads are measured in grains (gr). A grain is equivalent to 64.79891 milligrams. Each bullet has its own designated weight, with larger grain sizes indicating larger bullet weight.
**Types of Rifle and handgun Ammo**
There are thousands of various ammunition loadings for both rifle and handgun use. Most cartridges use a combination of grain, caliber, and gauge (for shotshell and pellet gun loads). Understanding these different types and loadings is crucial for effective range use and decision-making for the best caliber or shell for your gun.
For rifles, calibers range from.17 to.50, including common variants like.308 Winchester (7.62mm x 51 mm) for hunting and general purpose cartridges,.338 Lapua Magnum for large-game and long-range cartridges, to.50 Cal (twelve-point fifty-seven-seven) for heavier artillery usage.
For pistols and sidearms, cartridge dimensions have varied over history but roughly fall into sub-categories or gauges within categories; e.g. the ’38 Special revolvers as.38 inch; these categories are defined for pistols as 0.4-0.50 with some exceptions: The modern 9MMx21 (9-mm Browning Long) can hold varying numbers of individual, high-velocity shot capsules due to the shot spread among different shells being contained at 9 inches per unit. The smaller pistol’s barrel diameter must hold sufficient room for propelling rounds to ensure minimal resistance loss while firing as per these requirements.
Within handguns as well, common dimensions found are.35 calibur (0.45.38), in terms that can be observed to maintain consistency with similar other standard cartridges.
Calibre numbers usually refer weight relative to diameter measurement of that round compared against inches of diameter by mass within an area divided up over length.
What these tables represent is each standard category’s defined width dimension, measured per round area.
