Shell Question

[Mark Callanan]

I have a friend who offered me Game Bore shells from England
He says they are 67 MM per whats written on the box
I assume they are ok to shoot out of a 16 gauge 2 1/2” ?
The date on the box is 2/6/99 I assume that doesn’t matter
By the cross match 67MM is 2 41/64”
He seems to think its fine
That bothers me don’t want to hurt a Parker
He says the box also says Felt wad?
He says they measure 2 1/4" maybe 2 3/8"



Any thoughts?

Thanks Mark
