We had those and some Remington 513 T rifles in R.O.T.C. in high school back in 1950s. Shot them on indoor range. Had about 300 or more M-1 Garands, a few 1911 Pistols, Some .30 M-1 carbines, a recoiless rifle and bazooka. Can you imagine a high school nowdays allowing that
Mostly intended for military rifle teams and some indoor gallery practice. As a general rule, the U.S. did not train troops with small bore rifles; the service rifle and full power ammunition were used from day one.
That rifle is in very poor condition, which is a shame. In nice condition, they can bring close to $1000.
