100m we did not try, only did that with the Lampagyar with standard velocity ammo and it worked real good!
Could stay in the 9ring(diameter 10cm, about 4") at 100m with Schönebeck ammo all day long.
Now I rarely shoot .22lr at 50m range anymore, too boring deleting the 10ring from the target

Will dig my files tomorrow, have pics of that WW2 polish trainer anywhere.
