Estate Cartridge Co Hulls?

[Beaverhunter2]

I was given a bunch of Estate Cartridge Co 20 gauge once-fired hulls. I was told they were "the same as Federal paper-base hunting hulls". Can anyone confirm this or tell me where I can find some data for them?

Thanks!

All the Plastic Hulls with the fiber base wad, be they Federal Gold Medal, Field and Range, Top Gun, and Estate made by federal use the same data. The Federal Gold Medal has more data than the others combined so start with it.

The rolled fiber based hulls use Federal Hi Power load data ( 99+% of the time they are this hull )
If by chance they have a plactic base ( well less than 1% chance )
Most likely they are Gold Medal type hulls
But Federal also makes a hull that is called the Federal 1 piece hull

The gold Medal and the 1 piece hull have different base wad heights
But are of the same basic design

All 3 hulls use different load data
