In the "old days" at Bisley when 7.62 mm Target Rifles were nearly all converted something elses (no Swings or Metal Mickies in those days.), the received wisdom was that the No.4 was best at the longer ranges (600x plus) due to its inherent "compensation" but P.14s (Mauser action) better at the shorter ranges.
