Got my hands on one around 1968 and they were a lot of fun to shoot out to 200 yards.
If you tried to "Lob" one of the GI Ball ammo loads out to 300 yards with
the poor iron sights on the weapon and there was a twelve mph wind at the time
the odds of a hit in the first five rounds were slim to none, until you got the
"Kentucky windage" down pat.

As noted, I am another believer in no "Soft lead" bullets down the barrel with
the gas operation system that is used..... but what do I know?
