What are Alcan (fiocchi) #240 Primers..

[DonT]

I have a buddy who cleaned his basement the other day and came up with about 6,000 (60 tins) of #240 Alcan primers.

They look like shortened 209 shotgun primers but he said the last time he tried t use them they just fell out of the plastic hulls he was loading so he put them away, figured he got snookered, and didn't us them again.

Can someone tell me what these are and what they were used for? 
Can they be used in modern plastic hulls or only the old paper ones?

He is not real puter literate so I told him I would see what I could chase down..

Thanks in advance...

I'm not certain sure, but I think they were the same as the Remington 69 primer, which was a shortened version of the Remington 57*. It was made mainly for .410 shell, but could be used in any application that normally used the 57*. No hull made today uses the 57* size primer.
