Sierra Gamekings

[poecattleco]

I bought a part box of Sierra gamekings 150 gr (1840). I can't find any load data on the net and I don't want to buy another manual. Any help would be appreciated. I'm shooting a 270 and I have IMR 4350, IMR 4064 and IMR 4831 powder on hand. Thank you in advance.

There are some loads that would be close. Here is one off Hodgson site.
Pretty rare I get data for the exact bullet I am running
