What are the balistics of a 762 51 surplus round out of a L1A1????
If I zero it at 25 yards, where will it go at 100, 200 and 300.
Should I be zeroing it elsewhere?

Assuming:
sight-above bore 1.8"
2700fps
about 0.400 BC


_BC_ _MV_ 0 50 100 150 200 250 300 | YARDS
0.400 2700 > -1.72 1.51 3.49 4.05 3.07 0.38 -4.08 | > 150gr FMJ
2698 2587 2477 2370 2268 2166 2069 | fps, velocity
Far zero at 255.9, maximum 4.06 at 144.4, falling -0.11"/yd, angle 0.00217 rad


With a 50yd zero

_BC_ _MV_ 0 50 100 150 200 250 300 | YARDS
0.400 2700 > -1.75 0.01 0.50 -0.45 -2.89 -7.08 -13.00 | > 150gr FMJ
2698 2587 2477 2370 2268 2166 2069 | fps, velocity
Far zero at 135.6, maximum 0.51 at 93.0, falling -0.14"/yd, angle 0.00134 rad


You should really zero it at 200 meters and then use the marks on the rear sight.
