The most common type of large rifle primer is a Boxer. This type is used almost exclusively in the U.S., where loading ammunition is more common. While the Boxer primer can be expensive, they are a better choice for most people. Unlike their rifle counterparts, these primers are not difficult to use and are available in a variety of sizes. To help you choose the right type for your rifle, here are some important facts about boxers.
CCI Bench Rest Rifle Primers are specially engineered for optimum ignition under extreme conditions. The CCI Bench Rest Rifle primers are assembled with care, providing exceptional consistency and accuracy. These primers also feature an increased sensitivity design that allows for a wider sweet spot. They are also much easier to seat than older-style primers, and will feed more smoothly in automated or progressive loading equipment. Their clean-burning initiator compound will give you better accuracy.
Large rifle magnum primers are highly reliable and manufactured with precision chemical mixtures that ensure consistent ignition. Their tripod anvil design also ensures greater strike area and better sensitivity even when firing pin strikes off the center of the anvil. These components are also designed to function well in extreme temperatures and are rigorously tested before release. To ensure that these large rifle primers are reliable, Remington also tests each and every one of them against a variety of conditions.
In most cases, LPP and LRP are not interchangeable. You can substitute the LRP and LPP for each other in specific circumstances, as long as they meet the specifications of each type. In certain circumstances, however, LPP can be substituted for LRP, so long as the certification data shows that it works just as well. There are some exceptions to this rule, though. Unlike Small Pistol Magnum (SPM), LRP will not sit flush against the case head. However, they will fit into the LRP primer pocket. Large Pistol Primers, on the other hand, will seat too deep, and may even be punctured by the firing pin.
Small Rifle primer pockets can cause inconsistent ignition and can add significant pressure to cartridges. Lane Pearce cautioned hunters not to use Small Rifle primer pockets with Standard Rifle cases because the pockets could cause pressure issues. Cold temperatures make propellants harder to ignite evenly, causing a slight hangfire. The Small Rifle pocket also adds inconsistent charge to the bullet. This can cause a bump forward into the throat.
Fortunately, 6.5 Creedmoor brass has Small Primer pockets, which can result in better consistency and tighter standard deviations. Even a 20 fps difference between shots can mean inches on your target. It’s also easier to clean up large rifle primer pockets if necessary. It’s well worth the extra cost for these advantages. So, what are you waiting for? Take a look at this article to make an informed decision.
Magnum primers are made using two different chemical mixes. A standard mix produces a slower burning powder charge, while magnum primers have more explosive priming compound. They are not a good choice if you don’t reload magnum cartridges. While it might work, it can adversely affect your accuracy. Therefore, it is important to use the right type of primer when reloading a magnum cartridge.
