I'm a french hunter and i like a lot Remington (I've got 7600 Remington 35 Whelen...).
In france, i cannot find the answer to my question.
We can't use cartridges with leads in the wetlands (swamps, ponds...).
I'm interested for a pump-action shotgun 20 magnum gauge in woodwork for duck hunting (870 Wingmaster 20 gauge 28'' Barrel).
I would like to know the shotgun (870 Wingmaster 20 gauge 28'' Barrel in woodwork) with witch i can shoot all ammunitions (steel 20 magnum...).
Can i shoot a magnum cartridge 20 gauge with steel bullets in this shootgun ? Compatibility choke ?
I look forward to your response !!!

Successful continuation.
Please, escuse my english language...
Fabien.
