I saw many a M-16 round hit a tree and walk up the tree knocking off limbs and it wasn’t a linear path. I suspect the M-1 carbine round with a 1:20 twist rate tended to “drill” through you rather than wound.
TR was looking around an 11 inch thick tree in Cuba, and the tree was drilled by a 7mm Mauser, filling his ear with sawdust.
He said that if he had not been looking around the tree he would have been killed.
He also said that men who were shot by the 7mm Mauser if shot in the head, heart or spine were killed quickly, if they were hit elsewhere, they lived and recovered suprisingly quickly.
