You may notice increased light strikes/misfires, where the cartridge has been able to slip forward far enough that the firing pin is unable to strike the primer with enough energy to set it off. Headspace can change over time due to erosion and this can cause several issues. Headspace is the dimension between the bolt face and a limiting chamber feature which prevents a cartridge from moving too far forward in the chamber. A competent armourer will know the approximate round count for various calibres and can bore scope them when needed to assess their condition.Įrosion can also cause headspace issues. There are no set limits on barrel life but, if left for too long, the user will start to notice inaccuracies and possibly a loss of velocity or enlarged velocity spread. In this case, the weapon was found to have excessive fouling in the chamber and bore.Ī worn barrel can also cause a multitude of problems. A pierced primer which has been partially forced out of the primer pocket by high pressure. Weapons should be cleaned according to manufacturer recommendations and within their suggested timeframes. This was down to a failure to adhere to the manufacturer’s recommended cleaning and maintenance regimen. So, how often should a firearm be cleaned? I’ve seen weapons with several millimetres of carbon build up, which has led to significant overpressure. Of course, the latter two of these issues can have serious consequences. This can have a variety of effects, including inaccuracy, failure to cycle, failure to fire, or overpressure, and articles can become lodged in the bore. Most of the weapon problems I encounter are down to a dirty chamber/bore/gas system or moving parts. Below are some common issues I have seen in weapons that are mistakenly diagnosed by users as ammunition faults. Gun malfunctions are far more common than people think. Weapons, on the other hand, are often old, abused, or incorrectly serviced/maintained, the list goes on. The chances of rogue components or ammunition slipping through the net are small. We proof to British standards unless otherwise stated. Each ammunition component has been inspected by the manufacturer, by us at goods in, then again during the build and once more following the proof of a lot. At Primetake, we operate in an ISO9001 quality standard environment, as do most of our component suppliers. When I am called upon to assess an “ammunition issue”, nine times out of ten it ends up being a weapon issue.Īmmunition, when purchased from a reliable manufacturer has been given a significant quality inspection. I’ve been making and testing ammunition for many years and have spent the last 6 years as an Armourer and Ballistician in the defence sector. But there are, however, many weapons and system related issues that can cause what appears to be an ammunition failure but is actually something else entirely. When it comes to malfunctions in weaponry, people are quick to blame their ammunition for several reasons.
Paul breaks down these individual issues in detail and provides simple steps that users can take to avoid them. In this article, our Ballistician, Paul Bradley, offers some top tips on diagnosing problems with ammunition and identifying which malfunctions are caused by the weapon system, or in some cases, a combination of both. With ammunition issues, however, these malfunctions can range in severity from minor annoyances to life-threatening catastrophes. As with any product, ammunition can exhibit problems regardless of the quality of the product chosen.
