How a Gun Works – The BasicsBefore we can talk about the difference between the two, we really need to go over basic mechanics of how a gun operates. If you weren’t already aware, the way shooting a gun works is that you pull the trigger and the firing pin inside the gun hits the primer, which creates a mini-explosion that ignites the gunpowder, sending the actual bullet itself forward out of the gun.Why is it important to know this? The difference between centerfire and rimfire ammunition takes this chain of events into account, so it is highly important to remember as we continue on in this discussion.
The Difference Between Centerfire and Rimfire Ammo
Now, there are two types of ammunition that you’ll come across: centerfire and rimfire. According to this simple description from Hunter Ed, centerfire ammunition is most commonly used in rifles, handguns, and shotguns. The primer in this type of ammunition is located in the center of the casing base. This is usually ideal because it creates a bigger explosion, making it easier to shoot larger sized bullets from the casing with much higher accuracy.

With rimfire ammunition, the primer is located in the rim of the shell casing. Some people prefer this type of ammo as it does not have the same level of recoil as the centerfire variety. For those who have a tendency to flinch in anticipation, this can be a better alternative.

You can easily tell the difference between centerfire and rimfire by looking at the bottom of the casing. Centerfire will have a small circle in the middle, showing the location of the primer. (Hence the name.) In contrast, rimfire ammo will not have this circle.

Which Type of Ammunition Can Be Reloaded?The only type of ammunition that can be reloaded is centerfire. Rimfire ammo creates too much of an explosive reaction during shooting, which can damage the outside case and make it less reliable. Thus, it cannot be reloaded.I’m telling you it’s so easy with Lucky Gunner! The ammo shown on their site is guaranteed to be in stock and will ship fast.

Who’da thunk, eh? The more highly advertised ones – Cheaper Than Dirt, Cabela’s, et. al. – will put you on backorder forever and a day. But LuckyGunner – I ordered 500 shells that .45 ACP (hard to get in this “shortage”) – and there it was at my address. No backorders, no bull. Business as it should be.Yes, I’m telling my friends!
