257 semi custom Weatherby

[JamesWilson5]

100 grain ttsx will do great in that caliber. Want fragment either

I like 110gr Accubonds.... used them on game up to 600lb. Accurate and deadly. Tried 110gr Interbonds, they also shoot 1 hole groups, but the Accubonds work so well on game I've never been tempted to use anything else.

I use the 110 ab as well, and interesting that nosler doesn't make any heavier ab's for 257 caliber.

I have some 92 hammers for the wby but may use them in the 257 Roberts instead and stick with 110 ab and 115bt in the wby. The Roberts shoots the 100g Barnes really well though.

I have tried both nosler the accubond is my favorite. The bst they work but didn't exit with the couple I tried

I have shot a pile of game with a 117 RN—works great…used a lot of 100 grain and 85 grain too. Berger 115s shoot good in my Accumark LW…and my McMillian likes 120s and really light bullets like 85s..257 WBY is a devastating caliber

My weatherby liked the 115gr Berger HLVD and hornady 117gr BTSP when it had the 1:10 barrel on it. It shot 100gr TTSX barnes too.

If the absolute hammer had been out I would have tried that too.

There was something nagging at the back of my mind about long range cartridges loaded at the factory:

.257 Weatherby Mag. || .257 | 122gr | Remington SP Extended-Range

https://www.xxl-reloading.com/.257-Weath.-Mag.-.257-122gr-Remington-SP-Extended-Range

I still have a partial box of this in my cabinet. I tested this with good results then proceeded with reloading.

This is for the factory specs but there is quite a bit of reloading data also.

Enjoy!
