It very much depends on what you define as aim range, which is not specified there and therefore does not interest me.

BTW I see, the edition is from 1965... I wonder if it is possible, that during about 10 years between first model of B-10 and the edition of the manual there was some modernization of sight. It looks quite different than more primitive equipment of SPG-82. What I suggest is, that 1000 meters were used with early models from middle fifties and 1400 meters applies to newer ones of middle sixties. But that is only hypothesis

There are no data about that that B-10 or B-11 were modernised sometime. There is a table of shooting of these tools, the crew conducts shooting under these tables. The distance of 1400 metres - HEAT will overcome a shell approximately for 5 seconds.
The distance of 450 metres - speaks only about that that this distance of a direct shot for which it is not necessary to regulate a sight.
