I don't know if you are aware of it, but the 7mm is faster out of the barrel then the 264 win mag ... But the 264 come into its own after 300yrds and is faster then a 7mm weatherby... The 264 is starting to make a come back because Remington is chambering it in the sendero ,and CDL SF 700 Model rifles in this CAL. The bullets in 6.5mm have better BC ratings and higher sectional density for the same weight bullets in 7mm... Which makes for a very flat shooting hard hitting round. Something we need on the prairies where 300 yrd shoots are not out of the norm...
