I currently have a 257 AI on a tang safety M77, which was also a pain to get shooting good. Went through a lot of bullet/powder combos but finally got a load with the 115 NP between 1/2-3/4 groups with imr4831 and a little better with Barnes 100 TTSX and RL-22.
Also have a 25-06 M70 in a MPI stock that'll do 1/4" with the 100 TTSX and RL22.
Just put in an order for a 25 bbl to become a 25-06 on a Springfield 1903, and I'm being very tempted to order a 250 Savage bbl for my M70 Lightweight, that is currently a 243, and I'm also ordering a standard 257 Bob bbl for a VZ.24 I picked up a few months ago.
25's are for the loonies!
