Do you know anyone that actually neck turns brass for their AR15? It is kind of unheard of actually. After all, this is not a bolt gun in a National Match competition. But who cares if its not done, we just want to know if it matters, and what impact it has?
- K&M Neck turning equipment
- Redding Competition Full Length Sizing die with expander ball
- Neck tension is about 2 thousands
- Hornady Concentricity Tool, all bullets less than 2 thousands of runout (which means the bullet is not crooked in the neck of the bullet by more than 2k. within 1K is perhaps idea, but a few pieces could not get better than 2k, most where 1k.
- Length of brass trimmed to 1.750
- Brass prepped
- Federal Gold Medal Small Rifle Primers
I don't really like the K&M kit, although its one of only a few options there is for .223. The damn guide rod for the brass is like .001 too big, so you have to buy their expander and die adapter too, or you will gall the brass pretty bad. So they sell like a $45 carbide guide rod piece that helps with galling. What I don't like, is you can't buy a simply kit. They nickel and dime you a la cart for everything. And the guide rod is too big, because I don't know one expander ball made that can make the brass large enough to work on guide rod. Its .001 too big. So you have to buy their expander? Why not just make the guide rod for the brass neck .2225? or .222? What a giant hassle, it should be way simpler. Too complicated. Too expensive. This all has nothing to do with its performance, it works just fine and good. Once you get past the hassle of setting it up and all the time it takes, its a lot better.
