Disclaimer, as anyone who reloads will know, when reloading your own ammo you need to take precautions. The factors that come into play with producing loads yields an endless list- elevation, barometric pressure, humidity, lot of powder, lot of primers, tight chamber, loose chamber, rifling, so forth and so on. Just because a particular load works for us it may not work for you, work your loads up safely. KAK Industry takes no responsibility for mishaps just as any component manufacturer does.

    17-5.56 dies

    The dies are very simple to use with no experience in the reloading field. You simply clean and size 223/5.56 once fired brass spray a little hornady one shot one them and it works great. I realized 100 brass in a very short time with zero issues. I watched several videos of people trying different things with these dies and crushing the shoulders of the cases. I had zero waisted brass of the 100 I sized. Simply clean and size with a 223 die then lubricate them.

    Pricey but to be expected on a new chambering. Work as they should and KAK has always been amazing w customer service and product quality.
