anyone know when Winchester last made the silvertip? i've found a box of these silvertips, well not quite a box, they are loose so I don't have any idea about lot numbers of dates or anything. most of them look ok though, no rust or anything, a little bit of discolouration on a few that look like they have spent quite some time in a leather belt. I have no idea what grain they are... apparently they are supposed to be 220gr! don't look like it. I think I will pull one apart to check the powder and primer and then see if I can weigh the bullet.
