Berdan vs. Boxer If you plan on spending a lot of time at a shooting range, first ask if they allow it. Many magnum cartridges used large charges of very slow burning powders that can be difficult to ignite, especially in colder weather.

If they don’t, the reason is likely related to the reloading issue. This small bit of primary explosive sets off the much larger, and more stable, secondary explosive.Because any variance in this initial “explosion” can cause a much bigger variance in the secondary charge ignition, it’s important to use the exact primer type called for in published load recipes. Propellants are generally considered secondary explosives. This makes Berdan primers easy to manufacture because they are tiny empty cylinders that can be punched out of various metals, allowing the priming compounds to be placed inside afterwards. Refine by Caliber: .200 .300.

Any variance in primer ignition performance can result in pretty big differences in accuracy, velocity, and pressure.It’s not unheard of for different primer brands for the exact same load to create velocity differences of 100 feet per second or more and pressure variance of thousands of pounds per square inch.

You might be surprised at the differences from that one variable.Try to avoid handling primers with hands and fingers – that can interfere with ignition performance later.Avoid handling primers with your hands. Types of Bullets. And since ammunition is usually indicated by its caliber, let’s look into what that really is.

For example, a large rifle magnum primer or a 209 shotshell primer may contain only 36 milligrams of priming compound. This makes Berdan primers easy to manufacture because they are tiny empty cylinders that can be punched out of various metals, allowing the priming compounds to be placed inside afterwards.

You wouldn’t want to load a cartridge with a primary explosive as the firing pin strike would simply blow up your gun, and that gets expensive.

If you plan on spending a lot of time at a shooting range, first ask if they allow it. Standard primers are for cartridges of moderate capacity and velocity. These also offer a variety of sizes for very specific uses.Berdan primed ammunition is still common around the world, and works just as well as Boxer-primed.

Boxer primer cups have a small bit of primary explosive material inside the base. Most jacketed bullet loads for this caliber call for magnum primers, but lead bullet loads use regular large rifle primers.The bottom line is this. Think of it like lighting a birthday cake candle.

Boxer primers are relatively simple in comparison, and are the preferred choice among shooting ranges, sporting events, law-enforcement and the military.The Berdan primer features the anvil (with two or three tiny flash holes) as part of the primer pocket of the cartridge, while the Boxer has the anvil (with only one flash hole) built directly into the primer cup.

Or the reverse. Oils and such from your skin can interfere with reliable operation later. Don’t treat different brand and lots as interchangeable.If you are having any trouble with your priming “machines” whether it’s a hand tool, progressive reloading press, or something else, try a different brand of primers.
