sounds like a max load for a 25-06AI, don't think I'd be stuffing that much in a Roberts. Can you even fit that much in a Roberts case?
MAX load for a 25-06AI is 5 to six grains MORE, three grains more for the std. 25/06 in Sierra's latest.
3,100 from a 22" std. 257 is about it. Going to 3,200 in a 22" 257 AI is also going to be about it, since the 25/06 will get 3,330-3,400 depending on barrel length.
(Nosler lists a 100 BT from a 24" barreled 257AI with I4350 at 3,208 with 56.6gr water capacity)
