If I use the .308 expander, the .310 bullets fit just fine.
I have Never used a .311 expander, but I venture to say on the MN case it might be too loose.
But the .308 expander, works fine with the .312 bullets and does not buldge them out excessivly.
The Expander is Not Always the same size as the bullet.
Different calibers sometimes use a odd size expander, due the the Neck Wall thickness on certain calibers or cases.
What brand of cases are you reloading ?
Also, the expander must be set at the correct position to expand the neck inside in relation to when the outside of the neck is resized.
The inside and outside of the neck are not resized at the same position inside of the die.
