The 260-120 FP NOE is working in Dad's 25-06' , I'm yet to try it in his 257 Roberts .
The 25-06 I suspect is a 1-12" . If you can stay on the target up to 100 gr BTSP it's in a lot of trouble as far as you want to shoot . 115s make it an honest 3200 fps MOA to 400 yd , it was never papered further than that . 120s in Speer , Nos , and Sierra just didn't live up to the standards set by the lighter bullets moving out to a 2-2.5 MOA limits of desirable hunting loads . 700 BDL Varmint Special , 24" barrel .890 at the muzzle .
