Neck turning

[The Pumpkin]

I match the cutter angle to the case shoulder angle and make a light cut (0.001" or more) into the shoulder. I touch the shoulder with the cutter, then lower the mandrel a scooch(very precise measurement) more. I figure if the neck wall thickness is 0.015" so should the shoulder wall be. So taking 1-2 thousands into the shoulder wall is fine for me. I've got 10 reloads on the brass and have not blown a neck off yet.

I've cut cases a second time after 2-3 firings and found the area between the shoulder and the neck thickening from brass moving towards the neck. If your worried, cut a case in half the long ways and inspect.

Benefit is no donut.

According to my Funk & Wagnalls it's spelled skosh. D

As with everybody I have my opinion on how to neck turn. Here's mine. YMMV
Full length size (establish shoulder)
Expand (gotta fit turner mandrel)
Trim to length (Mandrel stops off mouth)
Chamfer inside (easier insertion)
Set neckturner for thickness and length
Run that baby on and enjoy.

I like the cutter lead angle to be a few degrees more than the shoulder angle so when you cut into the shoulder the angle runs out without leaving a step.D
