WILL ACCEPT ALL CURRENT FACTORY STEEL SHOT LOADS:

All Browning shotguns with the Standard Invector, Invector-Plus or DS choke tube systems, However, we do not recommend the use of Invector full or extra full chokes with steel shot. They pattern too tightly, and sometimes result in a "blown" pattern.

A Miroku 7000 should be the equivalent of a Browning Citori 325.

Until recently on the European Browning site there was this text:

"All hunting or sporting shotguns (over-and-under or semi-auto guns) by Browning, Winchester and Miroku fitted with the original chokes (Invector, Steel Invector Plus, Stainless steel Invector Plus, Teague, Briley, Midas, Diamond, Signature chokes) can fire "high performance" steel shot cartridges.

Tested at the Liège test bench (high performance 1370 bars) in accordance with European law on the use of steel shot"

Some good info can be found here and here.

Some brands sell hunting cartridges especially for guns only proofed for standard steel.
