| First time seeing these. Aluminum casing with a Total Nylon Jacket. Cheaper rounds I saw on cabelas site for .40sw. The description said that with the nylon jacketing it gets ride of the lead and fouling and copper residue. My concern is since nylon is so much softer is it going to leave more crap in my barrel that will lead to problems. Anyone experience any problems cleaning nylon out of their barrels? |

It's nothing special, but neither is it anything bad.
The Nyclad came about decades ago when jacketed hollowpoint pistol bullet designs were quite crude relative to what we have today. It was the time of the .38 Spl, before the wondernines and Glock totally changed law enforcement. At that time, expansion was all the rage, and the designs of the time needed about 1000 fps impact velocity to semi-reliably expand. The .38Spl isn't going to make 1000 fps reliably (even at +P pressures), and the jacket was seen as the limiting factor in getting expansion, because plain lead hollowpoints like the "FBI load" did expand. So designers cast about for ways to make a weaker jacket. One of those ways was to make the jacket out of nylon. Initially marketed by Smith and Wesson, it was picked up by Federal a few years later, and expanded to include 9mm and probably a few other cartridges. Interestingly (at least to me), the popularity of Nyclads coincided with the initial wave of Glock popularity. The crime lab guys absolutely hated Nyclads: the combination of a soft plastic jacket and the Glock's polygonal rifling meant it was basically impossible to match those bullets. It was also shortly after the time of KTW and the "cop killer bullet" flailing among media and lawmakers. Some folks could not grasp the difference between the teflon-coated, hard (solid brass), armor-piercing KTW design and the nylon-jacketed, soft, opposite-of-armor-piercing Nyclad design, and lumped them both together as "cop killers". They worked pretty well for the time, but were rapidly eclipsed by better designs. Unless they're cheaper than plain old ball, there's no real advantage to buying them. |
