Might as well get 25-06 then

I agree, the only problem with owning a Weatherby is feeding a Weatherby. Unless you reload or shoot it very infrequently it is an expensive rifle to shoot. If cost is a concern then go with a 25-06.

The BC comparison would do it for me.
the .25 in a 117 grain = .390
The 6.5 in the closest grain 120 = .450

Again I agree, easier to find ammo for the 25-06 too.

I agree 25 aren't BC monsters but not everyone is going to push the yardage mark where it matters. But just for agruement sake you can get 125gr .4886 BC 25 cal bullets if you handload

defeats its purpose.. keep it around 90-110 and push the mess out of it.

Concur why a run 80gr ttsx, still packing 1346 at 400, if I need more i might move to the 110gr AB's

mine is too dang picky.

My daughter is small/medium frame and she shoots a 25-06 and is deadly with it.
I have been impressed with her accuracy and confidence with the gun, so I got one with a muzzle brake and a sissy pad, I am 240 pounds and she calls me a wimp.
I swear these girl hunters are tough.

.250-3000 being getting the job done for 100 years.

Only load mine won't shoot sub moa is the AB's but its close

Vld's, 80/100 ttsx, 100sp, 100 Spitzer all sub moa.

Werid thing is 115 vld's group within a 1/2 0f the 80ttsx

You can go from varmits to elk with many rounds and calibers. Personally I think a 257 roy is a bit much for most women. Occasionally you have a real hard core woman hunter who doesn't mind, but from my experience most will tell you they don't mind the recoil but it manifests itself in the groups and shooting.

I would recommend a 243, 260, 7mm08, or 25-06 if a quarter bore is a must. I would get her a 270 before a 257 roy.

True but I like reducing margin of error in every way possible. I like a 25-06 nothing wrong with it. Personally I think its much better than the 257 roberts. My wife killed here 168 with a 25-06 and smoked it at 250 yards, deer went bout 5 steps.

If you want to get right down to it you can shoot the 129 Nosler LR accubonds with a BC of .561 I am waiting in line to try and get some of those for my 6.5. I just got some of the LRs for the 270 WSM but have not got to load them yet.

270wsm with 150 ABLR's

Since their regular ABs are off on BC, I expect the ABLRs to be too.

Well probably they are calculated, but probably not off by much

I thought this was gonna be about a 25 acp... I was gonna recomend a sling shot instead.

You keep holding dead on, and I'll keep enjoying having a bit of BC that actually cuts through the wind. And I dial to hit minute of angle, not minute of deer. There is a difference.

Not under 400. I'm not a sniper. I see, I like, I breath, I shoot

I'm not a sniper either.

What not under 400? There's no wind to hold for under 400?

Please don't whip out the weenies

Hard to beat a 6.5 but speed can equalize BC if you are willing to push a bullet fast and not worry about burning a barrel up. I haven't done that math because I don't care but you can make up some BC.

I think a .257 Wmag would be a cool gun to have...but I wouldn't want to shoot it but just to hunt with. I'd burn the barrel out FAST as I would have that bullet cooking!

To answer the original post...I don't have a clue, but you can always make a managed recoil load for her until she gets older.

.25-06 is pretty tough to beat. That being said, I'd go 7mm-08 for great ballistics and low recoil.

I've got a Mark V I might sell/trade if you're interested.

I really wanted a 257wby but I didn not like the ammo prices and trying to find it. I think 25-06 is a better option.

I personally don't like the sun in my eyes there for most set ups are north/south, second you are talking 8" with steady 10mph wind, that's not a difficult adjustment.

As I said you want to play long range over 400, build you a long range rig with optics that compliment it. I've had no issues shooting antelope, deer, and yotes at 400-500 with simple adjustments. You want to shoot 700-1000plus there are better calibers, and also better optics set ups. If you want to hunt 700-1000plus yards there are even better set ups.

But for a female that's not pushing the range past 400 257wby is a light recoiling highly effective round. Terminal on game performance is hard to beat with similar orlessor recoiling calibers
