1892 in 44 mag with a steel butt plate. ouch!
Weatherby .300 Magnum. 180gr Spire Points. 42 pounds of recoil will leave a mark after 50 rounds.
Ruger 338 win mag ...
But Browing Bar Safari 338 Win Mag ( With Boss ) not a mark , Thats may favorite ! Never a mark from that rifle . At least for me !
Mosin M44 with Yugo heavy ball ammo...
Be honest, people!
I've suffered visible bruises from my Mosin and my M590 when loaded with high velocity 3" slugs. Shooting magnum slugs 8 at a time is a bad idea.
