Seedy's old videos.

Yep, one bloke knows how to shoot. Some put the butt half off the shoulder at the top. Some on their arm and not the shoulder. These guys usually have the rifle flying out of their hands over the shoulder.

Other guys take the recoil but it obviously does hurt them.

That one guy was really good.

I don't think I would shoot it at the bench. That must hurt.

There is another old video where a couple of Norwegian guys shoot it with zero problems.

BTW 'Seedy' has reportedly two sets of ammo. One set loaded for more recoil than the other.

But the guys shooting it well also use the full powered loads.
