Which brand of sizing die pushes the shoulder back the most

^^^ The Redding Competition Shell Holders INCREASE the length of shoulder bump, NOT decease it, meaning, if you set your standard .125" decked shell holder to the maximum it can shoulder bump, these shell holders increase shoulder length by .002" (.004", .006", .008" and .010"), not decrease it.
They work great to adjust for different brass or freshly annealed brass.
Anyone who actually uses these knows this.
If you want / need more shoulder bump from a die, you'll need to do one of two things. 1. shave off a standard shell holder or 2. Face off the bottom of the F/L die. I've done both.

To bump it more you need it to go deeper into the die. If you shave off the top of the shell holder it allows brass to go in further, assuming you are camming over with the shell holder on the bottom of the die. I took off two thou on a flat stone to get the brass in further, bumping the shoulder back two thou more.
Great discussion on shellholders, but it is on a progressive, so I don't have that option.
I was trying to size fired 556 brass to fit a Compass Lake Barrel, and I couldn't do it with my progressive set up. I figured it might be the plate, so I tried on my Zero as well, with the same dies, but no dice. Anyway, I went through every 223 die I have, and the only one that would get it small enough, on the Zero and/or the Mark 7, was Whidden. It did it with room to spare.
Since the CLE gives you an absolute number goal, it isn't hit or miss as much as it is a pretty short chamber. It's just about equal to virgin starline 223 brass.

What a clusterfuck…
Redding dies push the shoulder back the most. Forster the least. Redding bests Forster by about .004”
