Ruger 77 tang safety receiver cut

[matthias]

Last gun show a friend found what looks like a PTG aics bottom metal for a "ruger magnum"

I checked the bottom metal against my ruger 77mk2 magnum and the magazine cutout in the receiver is not long enough.

If someone has a 77 tang safety magnum I would ask if they could measure the length of the magazine opening in the bottom of the receiver. Just oal without the sheet metal magazine body.

Thanks , Matthias
