Hi Dale,
I used to have one, but not now. But still like the quarter bores.
Lovely Mark V American made one with delightful wood.
100 grain bullets at around 3600 fps and 120 s at 3300!
Was very good on foxes, but, never liked the results on deer at the ranges i used it at.
New brass was cheap ish from SGC. I was given 100 once fired cases but they wouldn’t chamber in my gun, however, an American friend sent me a collet body die that sized the cases right up to the belt, so i was able to use the fired brass.
Would be fine for longer range deer shooting, or destroying foxes at any range,imo.
Regards,Ken.

I considered one but the brass is costly and in the big game weights (117 and 120 grains) it used about 25% (? iirc) more powder than a 25-06 to get another 150 fps. Not exactly efficient. The draw for me was that i was offered a top of the line Weatherby at a very good price. It was just too much of a mouth to feed for the work I'd get out of it.~Muir

Muir,
I think you’d get nearer 300 fps extra over the 25-06, but, still acedemic really.

I took a look at Hodgdon's data after I posted that (to make sure I was not being a complete fool) and the difference with top loads with the 117 grain were about 150-200 fps. (3050 VS 3200-ish) Still, as you said, it's academic. Moreover, in my estimation, a poor trade off for that much of a powder increase. I believe the term "over bore" was first coined in reference to Weatherby chamberings. ~Muir

Hi,
I was cheating because i was comparing my actual .257 WM figures over the chronograph against 25-06 theory figures.

I went by the book but real life always works.~Muir

I too have always admired the .257 Weatherby. Per the Barnes manual, a .270 Winchester with a 24" barrel can give you the following: 110 gr TTSX 3507 fps, 95 gr TTSX 3673 fps, and a 85 gr MPG at 3801 fps! I have shot deer and antelope with the 110 gr TTSX, awesome results without the blow up of the soft ballistic tip type ammo. Accurate, deadly, and no horrific damage to the meat. Given the above, why bother with Mr. W's .257?

Exactly, AGOW,
My RW was a very nice rifle to look at though. Lovely wood and extremely well made.
