"...zero it for him..." You can't. He has to sight it in.
"...risk of a "bullet vaporization"..." That can happen with varmint cartridge bullets shot with the wrong velocity or rifling twist, but doesn't happen much with larger bullets made for penetration. Anyway, loaded ammo is using typical big game hunting bullets. Accubonds and Partitions. Those don't "vaporize".
"...hottest commercial 7mm cartridges..." Kinda doubt that. Midway shows 5 brands of expensive(starts at $60 per 20) factory ammo. All but one are on 'No Backorder'. No stock at Graf's either. That might be about the time of year though.
"...what I think more likely..." He just missed altogether caused buy a lack of practice. The recoil is stout. A 140 grain bullet at 3425 FPS out of an 8.5 pound rifle(An M700 SPS SS weighs 7 5/8 pounds.) has 25.3 ft-lbs. of energy. A 160 at 3200 FPS out of the same rifle has 29.4 ft-lbs. The 7mm Rem Mag runs at lower speeds and therefore has less recoil.
