Want to zero an as issued No 4 Mk 1 that is scope mounted. With a 200 yd zero what will the approx come up elevations be for 300, 400, 500 and 600 yds? If data is with a 100yd zero that would still be useful. If data is in meters I can convert. Will be using Greek HXP ball and South African 1980's ball. I may not have internal scope elevation for 500 & 600 yds but want to see if it is possible. Thx
