Just purchased a 257 Weatherby mag. To say I'm impressed with the ammo is an understatement. I got the cheapest ammo they made $33 dollers a box. Measured each shell to the ogive measurement and they were all within .002. Weighed each loaded shell (bullet, case, powder) and they were all within .5 grains of each other with 15 of 20 being the same. That's handloading consistent. I could buy loaded ammo for $33 a box or brass alone for $32, just hope they shoot well.
