Estate 12 gauge Heavy Game Load

I have 4 boxes of Estate cartridge 12 gauge Heavy Game load. These are 2 3/4 shells with 1 1/4 oz of 8 shot. 

I don’t know much about these but the shells are in excellent condition to make me believe these are modern shells even though the boxes looked a little aged. 

$100 or best offer. PAL required. Meet up in York Region.
