Bullet grains
--------------------------------------------------------------------------------
Hi all, I'm still relatively new to all this "gun stuff." While I have picked up a lot over the past month, one of the things I'm still stuck on is bullet grain. It seems like the higher the grain, the more velocity and therefore recoil the load should have. Is this the case or not?
Let's clarify some terms:
1. Bullet - The projectile which is fired from a firearm. In the United States the weight is typically measured in grains. Example: the standard full metal jacketed bullet for the .45acp weighs 230gr.s.
2. Cartridge Case - The usually metal (brass, aluminum, steel) cylinder in which bullet, powder and primer are contained to create a whole cartridge.
3. Powder - The propellant contained in the cartridge and ignited by the primer, pushing the bullet into and out of the barrel. Also typically measured in grains in the United States. A popular light target powder charge for the .38 Special with a 148gr. lead wadcutter bullet is 2.7-2.8gr.s. of Bullseye powder.
4. Primer - The explosive compound which when struck by the hammer or firing pin ignites the propellant.
5. Cartridge - The combination of bullet, case, powder and primer which is loaded into the firearm as a unit.
BULLET weight and velocity are typically inversely proportional. A heavier bullet will have LOWER velocity with the same powder charge than a lighter bullet.
Buy yourself a copy of "Cartridges of the World" or a reloading manual (Hornady, Sierra, etc.) and all of these things will be explained to you in great detail.
