You will find that anything over 40 degrees is pretty well useless and VERY touchy with sizing. If you take a case with say a 50 degree shoulder, it could collapse the case just seating your bullet if the dies and chamber of the dies are not set up exactly perfect.
A friend of mine got talked into a 300 WSM improved 50 degree about 2 years ago. He cusses it every time he reloads it. But he loves to shoot it, at least, when the ammo will fit back into the chamber!

I have had several 40 degree wildcats, and they work fine. However, I think 35 degrees is just about perfect for most applications.

I am thinking about building a cartridge with a 45 degree
shoulder on an unbelted mag case. Would it make a difference if you used collet dies for working the cases?

Ackley looks to be pushing the limit. I think the 6mm Ackley is 40 degrees.

I don't know if he pushed the limit or not I'm going to see.
All of the Ackley calibers I have heard of are 40 degrees.I have the 6/06 A.I. and think 5 degrees more shouldn't be that critical, i believe it will be more effecient especially in a large case.
