I am starting to reload for my new 257 wby mag and i would like to run the 110 gn Sierra tipped gamekings but i cannot find any data on this load.
Has anyone used this bullet out of the 257 wby?
 
Email Sierra they will provide you their data on it. I have had great luck in the past with Sierra CS.

I gave that a shot this morning, unfortunately they have not yet done the load data for the 257wby with that bullet. They just recently completed the 25cm and the 25-06. There recommendation is to use the 117gn data and make changes as needed.
 
Should be able to use data for the 110 nosler AB. Or just stuff a bunch of 7828 in there and rock on 😀
 
I used Nolser AB data to start, and settled at 64.0Gr of imr4350 (max). I think they are a great bullet in that cartridge.
 
I ve used 110 AB for years but tested the 110 TGK for accuracy last fall. It shot equally well as the AB, 3/4 moa ish, at same POI and velocity; 68 grs R26 = 3500 fps. Work up to this, it’s a hot load and your rifle may not like it.

Haven’t yet shot a critter with 110 TGK so that’s still an unknown. AB does put the hurt on deer/antelope!
