Oh....7mm/300 Win?

I'll still take the Mashburn. Like the longer neck and forming that shoulder is done with a single pass through a die.No more work than the 7mm/300 for me. i really don't mind it. Not an issue.

It's easy.

You are right though...I used to make 7mm/300WM cases with a 7 RM neck die back in the 80's...... I just never wanted one.




The 280 Remington is overbore.

The 7 Rem Mag is over bore.
