If Carlos Hathcock had a McMillan Tac-50 well who knows?
I think he used a Winchester Model 70 .30-06 using an 8-power Unertl scope. Primitive by today's standards. **Once he put a round through a Viet Congs sniper scope while the two men were looking at each other, several hundred yards apart. The bullet went through the enemys scope and into the snipers head.**
*White Feather* took down the infamous *Apache*, a female Viet Cong sniper. Gunney possessed legendary skill at stalking his targets for days, inches at a time. Going without food or water.
**At his retirement ceremony, he was given a plaque with a bronzed Marine campaign cover mounted above a brass plate that reads: There have been many Marines. There have been many marksmen. But there has only been one sniperGunnery Sergeant Carlos N. Hathcock. One Shot. One Kill.
God Rest his soul. He died too young.
