I finally got back the mounted tusks of the big boar I shot last December during a drive hunt. It was a big and impressive animal weighting 106 kg (234 lbs.) dressed, which would indicate a live weight of 130-140 kg (290-310 lbs.).
Both tusks were broken and about to be resharpened. It's a pity but very common with big, old boars. One wonders how long the tusks were when intact.
I've laid a 9,3x74R round (the same as the one which felled the boar) alongside for comparison.
