Oh, picky, picky, picky: M80 Ball may not be up to today’s standards but we got good, solid hits out to 500 meters all the time in our time touring the area southeast of Danang.
Don’t throw it away yet..
I wouldn’t throw M80 away, but we’ve got much better stuff available now for long-range shooting.
I will say, in the hypothetical scenario where the proverbial poo-poo hits the rotary oscillator and I have to grab one of my rifles off the rack to head into the field and go to work with, I’d have a hard time not grabbing my 75-year-old Garand and every clip of M2 Ball I can carry. So I do have some fondness for the tried-and-true stuff.
Or I might grab my hand loads where I duplicate M2 Ball (150 grain bullet over 50 grains of 4895), but with Hornady SSTs instead of FMJ. I’m not a signatory to the Hague Convention, after all, so might as well use expanding ammo if I can.
