I have a carbide case neck trimmer. Typically on my rifle cartridges I clean the brass, clean out the flash hole and primer pocket, cut the brass to size, chamfer and debur. Now I want trim the neck.

The question is how far down the neck to you trim? Just the width of the cutter blade or the whole lenth of the neck? I would think from the mouth down to where the bullet seats but I am guessing at this time. Who out there is an expert case neck trimmer?

That would be one way to approach it, providing the particular cartridge isn't "short necked" and you have to trim all of it, anyway.

I always seat my bullets a minimum of one caliber diameter deep, regardless of how far off the leades the bullet will be. Must clear the magazine well by about 1/8th inch,also. This means the necks are usually pretty well used down to the top of the shoulder, or maybe just a tad into the shoulder. Also, my cases are partially sized down to where the shoulder is just slightly kissed and there is 1/16th to 3/32nds of neck left unsized so that it makes a snug chamber fit. This helps in centering and headspacing the cartridge properly in the chamber. That means when I outside trim, it is down to the slight bulge left on the neck from being unsized.
