I ran the figures for the 6.5 CM 147 grain moly-coated match projectile using the temperature stable load of H4350 mentioned earlier by Jordan which is slightly above the maximum load recommended in Hodgdon. Sighted in 3" high at 100 yards it drops at 350 yards 10.1" 10 mph drift 6.3". The .270 140 grain TGK hunting bullet drops 5.8" drift 7.7", the .270 130 grain Classic Hunter Berger at 3100 drops 5.1" drift 7.4". So the .270 has far less drop (4.3" and 5") with the hunting bullets mentioned than the 147 grain match bullet in 6.5, but the 6.5 147g match bullet has 1.4" less wind drift than the 140 Tipped GameKing and 1.1" less wind-drift than the .270 Berger 130 Classic Hunter. Now if that 6.5 147 grain match bullet was engineered as a hunting bullet to perform well on game its b.c. would drop probably to the point that wind-drift would be similar and its drop would be even more. The .270 bullet also has 10% more cross-sectional area for a bigger wound channel.
