I'm not familiar with the Sako 75...
SFAIK, it would take the rupture of the case itself to truly create a hazard. I've not heard of that happening with U.S. factory ammo.
Some of my father's .22-250 handloads were a bit "ambitious". I shot some through his 1974-variety Sako; on one shot, the primer fell out. (Seems he was nearly two grains too much on the load.) Anyhow, no gas blew back.
If, like me, you're already four-eyed, just get tempered lenses. Otherwise, poly-carbonate (? I think is the name.) lenses are very impact resistant. I'd suggest a light yellow tint.
