The 110gr .257” Nosler Accubond is only 110gr for a reason. I’ve got some Hornady 110gr InterBonds that are 2-2.5 MOA from both the Roberts and Weatherby as they are just too long for the 1/10” twist.
Swift only makes the Scirocco in 100gr. Likewise due to the 1/10” twist of most cf .25’s.
I doubt you’ll ever see a 120gr tipped boat-tail .257” bullet. Same reason you don’t see a tipped 175gr .284” hunting bullet.
The bullets that most excel in the .25/06 and .257wby are the 80 and 100gr Barnes TTSX. From the .257wby, the 80gr can hit 4,000fps, 3,800 from .25/06. At hunting ranges, (400yds), it’s a Point and shoot proposition.
The only problems I have with my .257Wby is that it only has a 24”bbl, and weighs 10+lbs.
The last year I hunted with it extensively, I got bursitis in my elbow from carrying it to and from th3 shooting house. My Roberts only weighs 7lb with 2-7x Leupold, sling, and 5rds.
Guess which gets hunted most???
The reason the likes of the 6.5 Creed becoming so popular for hunting, displacing the magnums, is the prevalence of good, inexpensive laser range finders eliminating range estimation errors.
