Can I use a Hornady neck sizing die for 7mm on other cases that are 7mm??

When I was loading for a 7 X 57 I purchased a Hornady 7mm neck sizing die. Can I use it for 7MM-08, 7-30 Waters?? I shoot only cast bullets in my G2 Contender for 7-30 waters. I shoot 120 grain cast bullets in my 7MM-08 Rem.rifle. Your comments are requested. Thanks so Much!!!

Perhaps for the 7mm-08. The 7-30 Waters should be 5mm too short but it might be enough to hold a bullet for single loading.
If you use the die with cases sitting on top of a nickel on top of the shell holder, you can probably make due.

Do you actually need to size the necks? As fired from a Contender, are the necks expanded too far to hold the bullet in place?
