European 7mm barrels
Some Euro manufacture 7mm barrels have a groove dia. of .285 vs .284 in the US. Anyone have any experience with .284 bullets in Euro barrels, lower velocity, poor groups, etc?

Roll EyesMe thinks that by the time that bullet is completely swagged into the rifling by the force of the expanded gas it will have swollen the .001" in diameter. hammering roger
