Boatanchor: That indeed was a lucky day for you.
Reminds me of a lucky find I came across about 25 years ago.
I was driving south on Pacific Highway from Tacoma, Washington doing all the pawn and gunshops thereon when I came across 10 twenty round boxes of Norma 220 Swift brass and they were on close-out for $3.00 per box!
Needless to say i bought'em all.
Still using that brass in one of my Swifts today (about 4 reloadings so far).
I find it pays to "get around" and check things out.
Hold into the wind
