I recently picked up a Ruger No 1 in 257wby with a 28" barrel.
I loaded up a pressure test with IMR 7828 ssc and 110gr nosler accubonds.
Below are the results, never had any kind of pressure signs:
69.0- 3,493 fps
69.5- 3,549 fps
70.0- 3,554 fps
70.5- 3,550 fps
71.0- 3,631 fps
71.5- 3,628 fps
*Book max is at 71gr
I'm pretty excited about this gun and load combo. Going to do accuracy testing next and plan to sight in at 250 yards.
Does anyone have any experience with Accubonds at these speeds? Interested to hear some real world experience!
