My first .257W was a converted Mod 700 classic in 25-06. Bolt face opened up, M16 extractor, rechamber. Back then Federal loaded the Nosler 115PT. It was so stinking flat out to 400 that I didn't even reload for it. I shot a Blackbuck at a tad over 370yds in Texas, just held on hair with a +2"@100 zero. I then shot a Black Hawaiian ram at 250. My outfitter offered me $1200 for it and the scope ( a Tasco WC 2x10 they made back then) I sold it like I had stole it! ha I later bought a custom Mark X, 10yrs later, loaded the 100TSX. Shot another Black hawaiian around 150yds, but through a hole in the scrub. Same guide, he bought that rifle too! ha. A good, properly loaded 25-06 would have done what either of those rifles did, and a .257 Roberts Ackley Improved will too, and be more fun to play with! I like the really flat shooters for small antelope, threading through the brush, making head shots ( I popped a big white Fallow buck at 110yds with a 6.5/284, another flat shooter, with the 120BT who thought he was hid. All I could see was about 2" of eye/temple. It was "Shame on Him" time!) A .240 Weatherby with the 90gr X bullet did the same thing, so did a 6mm/284. No reason not to get the .257W, and the S2 is probably a good one to start off with. You can always upgrade ( which we all seem to do anyhow! ha) Good luck to you Pard.
