Has anyone used the Sierra Gameking Tipped 110 Gn in 257 wby mag?

[gmcclellan]

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’ve had great luck with 110 ab in 257 wby using h1000, 7828, rl26, n560
