Hey guys
I picked up this full box of 25 rounds XM257 at an estate sale today.
I have seen the W-W lot codes explained for centerfire metallic cartridges,
but this lot code is different.
Can anyone tell me about these rounds? I am interested in the date of the box,
scarcity, value, and history behind the XM257.
Markings should be clear but here they are
Hulls Marked
WCC-1-2
NO. 4B SPECIAL
XM257
Box Lot No. is D80ED92
SKU is GQ1307
Headstamp is W - W over 12 GAUGE
Here are the pics
I’m sure John or Dennis or someone will be along shortly to educate me.
Thanks
