Home Forums Reloading Big Game Rifles 257 wby whats your bullet and why?

Norma brass(which has a larger capacity hence the large load of powder IIRC 90 gr water also running moly coated bullets)3.190 and Federal 215M primers

I am in high hopes that my new bullet for my 257Roy will be the Nosler 100 grain Etip. Why? Well, I'm hoping that it will shoot more accurately than what I have had thus far, and I believe it will be as close to ideal as one can get for a bullet that will perform under those velocity conditions. Keeping my fingers crossed.

To which post are you referring? My 120HP load at 3300 fps is straight out of the Hodgdon Manual:
120 - 69.0/IMR7828 - 3.17" loa - 53,000 cup


.

IME .257 Weatherbys with the factory freebore shoot better with non-boattail bullets. Mine shoots the Remington 87 HP far better than the 87 BTip, the Speer 100 SP better than the Nosler or Sierra 100 BTs, and the 120 HP Hornady is the best 117/120 bullet I've tried in several Mk Vs. My custom .257 has no freebore and shoots everything well.

While I used 100-grain bullets for years in my .257s, I finally gave up trying to find one which always worked well at 3600 fps. The closest was the Nosler 100-grain Partition, but even it caused bloodshot meat at under 125 yards. The slightly slower 120 shoots as flat, kills very well and doesn't damage as much meat with equal bullet placement.

He was refering to my load which is over max but as stated brass is large(90 gr water capacity rather than 85gr) and I'm running moly coated bullets

300

Have you tried the Barnes? I have yet to chrony my Etips but I speculate as to whether I can get equal velocity?

100gr Scirroco II's/H1000 @ 3600fps land sub-moa as far as I care to shoot...

I shoot the 115 Grain Partitions in my .257 mag. It's much more accurate in my rifle than the 120. I don't trust the Sierra stuff at very high velocity. It's an old bullet that has always kicked butt for me so I don't need to experiment much. Good Luck! Dee

One of the good things I can say about my .257 wby is it shoots everything between .75 and 1 inch. I havent found a load yet that produces half inch groups, but it shoots VLD, TTSX, TSX, Accubond, Scirocco II all of them right at or just a hair below one inch. I shoot the VLD for deer, and my buddy will be using it with the 100 TTSX in Africa.

Nitis,

I have tried the Barnes TSX in 100 grain weight. It has been o.k. as far as accuracy goes, but nothing to waste the paper to write home about. However, in all fairness, the gun has given me its share, and many other rifles share of problems. I finally sent it back to Weatherby and they recrowned it for me and then sent me back the test targets...the best, which was really nice, was the TSX. When I got it back I had it bedded into a fibermark stock and started playing with it. I didn't play very long before I got distracted with other things and just now getting back to it.

Anyway, the TSX shot o.k. and velocity was good - 3,600 fps, but the fact that Remington bought them out and the fact that I have always liked Nosler products has prompted me to give the E-tip a try. I think I will start with IMR 7828 and see what happens.

Thanks.

Here's what I use and it works for me:

.257 Weatherby Magnum - Deer Hunting Load

Primer: CCI 250 LRM
Powder: Reloader 22 - 64.5 Gr. **MAX**
Bullet: Nosler Partitions 115 Gr. - BC 0.389
OAL: 3.180"
Case Usage: Weatherby (Norma)
Remarks: Lee 2nd. Edition, P.304 +/- 3,200 FPS

Don't know if I'm getting this velocity since I haven't checked it with my Chrony. I have a 24" barrel on my Vanguard. I do know that it hits hard and stuff goes down if I do my part. Dee
