6.5 Midrange Precision Round
SP45
Member Posts: 1,761 ✭✭✭
I am building a match rifle for midrange distances. 500 to 600 yards. I will be using a Remington 700 action. I am only interested in the 6.5's for a lot of reasons, barrel life, Bullet SD and efficiency. (I have others in 30 cal.) What velocities can I expect from the 250 Savage case and the 257 Roberts case both being necked up to 6.5. I will be using the heavier match bullets.

A 6.5x.257 is pretty much a 6.5x57 and ought to do similar to a 6.5x55 with a 142 gr SMK at 2800 fps in a strong modern action.
Sounds like a lot of trouble to me. How about a 6.5x55 or a 6.5x47 Lapua? An old standard and a new wannabe standard.
I haven't a clue as to what a 6.5x.250 Savage will do.

For that matter, why not just a .260 Remington? The ballistics are similar to the 6.5X55. I would think that it would definately out-perform any 6.5 that is based on the Roberts or Savage wildcats.
On a modern action, 2800 fps would be a start with 140/142's. 3000 fps will put you just right.

Of course it is had to beat the 30BR:

But the 6mmBR still holds most records for midrange:
