I have been think about this rifle for a few years. It has went from a 6mmbr or 6mmPPC 300 yard Bench gun to a 1000 yard F-Class rifle.
Here is one that is just about what I am looking for but his is a bit shorter barrel than what I am looking for.
.284 Win Tactical Hunter
I like the 284 and in the 7mm it is not all that bad of a barrel burner. Now neck it down to a 6.5mm and yes 1000 maybe 1500 and you have a $300 tomato stake. If I were to go with a different cartridge it would be a toss up between the 6XC, 6dasher or a 260 Remington Ackley Improved. At one time I was going to use the 308 but I like the ballistics I can get from the 180gr Berger in the 284. That and we all know that the 308 is barley a long range round, yes I know the USMC and the US Army use it. But why handicap your self from the get go.
