    Looked at the ballistics of one when looking at a "Quarter Bore" seems to be scarily fast to me.

    Interesting to hear what people find though

    as a very smart and experienced man once said to me,,avoid ANYTHING Weatherby,,just trouble with brass, costs, esp. feeding due to shoulders, etc. etc.

    as another very smart man also said to me once, I'd like a .257 Roberts...

    Flattery PV, will get you into places you may not find it as easy to extricate yourself from as you'd like it to be

    Have to say, when I was out in Africa, the PHs used to dread people who arrived with weatherby magnums! Too fast for decent penetration. Bullets break up and as someone said to me, instant flinch in a fancy stock!

    Best wishes,

    David.

    Look at the load data for a 257 WNY and the 25-06. In 100 grain bullets you get 200 fps more but need almost 50% more powder to do it at an increase of 5000 psi. Brass is expensive. The 25-06 is 'over bore' as it is. A 257 WBY is more so.

    That's the way I look at it too, I have a 25/06 love it to bits dynamite accuracy power to spare, it shoots 115 Berger VLD's under .5MOA at 3100fps still has over 2100fps at 500 metres, The 257 mag shoots like a laser I would like one too a bit like a Ferrari expensive to run,
    In reality a 257 Roberts would be a better calibre I want one of them as well and a 25/20 have the whole range covered, also the 25/06 and .257 Weatherby need 26" barrels to get their performance the Roberts is fine with 22"

    I shoot 257 weatherby hard to get brass I got it from Germany but it can be hard to get brass for reloading a times . It shots fast and flat I shoot mine with r22 and Speer 100g spbt at 3425fps drops reds ass if hit by lightning plus its good long range on all deer. Ask Buggsy on her he shot some red stags with it on the hill one day he was very pleased with the performance at 300+.

    I would have thought that in NZ there would be no shortage of 25-20's. Australia is the second home of that fine little cartridge. I bought two of them from a dealer there.~Muir

    I had one it was great fun for a while especially on foxes 4000 fps, uses a lot of powder for no significant advantage. You can neck down 7mm rem mag cases a little short but never caused a problem
