The seller stated over a week ago that he slipped on ice and was 'down' for several days, plus the friend who will receive it planned to be out of town for Christmas.
My friend returned home today and found the well-packaged box of ammo on his doorstep.

The old .303 headstamps are: "D/ Z" "42" and "B P D" "952". Looks a lot like what Samco sold last April.
A second seller took about two weeks to get a sealed pack of pulled .311 bullets here, so it is just a hectic, slippery time of year.
Even really good people make mistakes or get disorganized then get hurt.
Being the burned "pot" (disorganized), it's not really my place "to call the kettle black", and both prices were quite reasonable.
I thank guys for your input and concern.
