So, I finally received my new Sinclair Concentricity gauges thanks to BC and with it comes this catalog with all kinds of tools for reloading. I came across this section on neck turning accessories.

So, my question is..... how important is this neck turning for reloading. All my brass is Remington at this time and without measuring it , would this be something I should start doing as part of my reloading routine. I don’t do any competition shooting but I have intentions to shoot at 200, 300 & maybe 400 yards this summer. Would this be just another tool to sit on the shelf collecting dust or is there something more to this neck turning ?...

Neck Turning is needed in my opionion for tight bores, and for my 300RUM. I had such trouble getting good remington brass, I had to neck turn. But for 308's and such, I usually can cull to find good brass.

I have the neck turning tools for 7mm and 308, and rarely do it anymore. Its better to cull the brass. Or better yet, just load and sort out good bullet runout and back bullet runout. Use the bad (>.004") for fouling and such, and good for long shots and hunting.

What's the difference between neck turning and neck reaming? I have a reamer for 7mm. Is there a great difference between the two, and why? Is it because you can remove brass at certain places on the neck by turning, and not by reaming for better concentricity?

When you neck ream, you are removing brass from the inside of the neck of your case. When you are neck turning, you are removing brass from the outside of the case. With the neck turning, the brass is trued, as in, all inconsistancy is cut from the case. This in turn, causes your bullet to release from the case with more consistancy. For hunting purposes, this isn't really necessary, but for bench rest, that extra 1/4 inch of accuracy could be the difference between winning or losing your match. If your fired cases neckswill easilyaccept a bullet before you resize them, then neck turning is unnecessary. If you can't get the bullet in the fired case, then the turning is an option.

Neck turning alone may not help you much.
If you weigh each case and sort them,uniform primer pockets and debur flash holes, and do all of the other things benchrest shooters do for fun, you may see results

Thanks guys, I never really thought much about sorting my brass but will give it a try and as for neck turning, I’ll let it be for now...
