60-70 yards with a scoped rifle and a slow moving car (SS agents were walking alongside.) is indeed very make-able.
I would compare it to an NBA player hitting 3 consecutive Free Throws.
Again, very easy and about 80% probability of success, if not higher.
I know a number of people that could do that with a pistol, mostly .357 magnums. They empty their revolvers into a 2 1/2” circle at 100 yards. 60 yards would be quite easy.
