Yes it does! Capacity is 71 grains of water depending on case lot......Rich
About twelve grains of water less and matching .264 velocity? What pressures to do think you are running?

What does changing the shoulder angle do? Other then make the case shorter. I'm still in the learning process of all this.
Unless you give consideration to case dimensions, it is not correct to say the shoulder angle increases case capacity.
If you take a SAUM case that has a 30° shoulder and push the shoulder/neck junction back to create a 40° shoulder and to make the neck longer, you have decreased the capacity.
Let me make sure I'm understanding you right. Your really moving the shoulder/neck jct back to get the 40°. The length of shoulder you loose by going from 30 to 40, is moved to the neck. ( not the exact mesurement, but close) Is that how your making the necks longer?
Yes I see the big picture now..lol
I deal with degrees and lengths everyday. My mind kept telling me that the extra brass had to go some where and I couldn't figure out where it was going.
I realize now how it is done. Thanks for explaining that for me.

You were correct about the brass going from the shoulder to the neck.
I have a 6mm Wildcat. I change the shoulder angle from 17.5° to 26° by moving the neck shoulder junction back in a form die. It makes the neck longer.
I have a 7mm and a 30 caliber Wildcat that I push the whole shoulder back .225" with form dies. The necks get real long on those two.
Ok thanks guys
So it just depends on what benefits the caliber you are working with. I think I get it now.
